First of all, motor drives went out with film cameras.
Second, AI Servo autofocus mode is explained in your manual at the bottom of page 65.

No, it seems like a pretty normal day.
It seems frustrating when some users cannot articulate their true questions.
Have you purchased a motor drive for your digital camera?

Gyrob, the camera's doing what it's supposed to. Bob gave you information about how to work it out yourself, which is generally more useful than just telling people the answer, as next time you might know where to find the information yourself. On the internet things often come over seeming more blunt or less friendly than intended, try not to take offense when it happens.

He would not have to worry about taking offense if people would take time to just post a reasonably friendly, helpful answer. Problem solved. If he did not like the question - move on and ignore the post. People do it all day long.

First of all, Canon refers to it as "drive setting", so they evidently don't agree with you.
Second, the explanation of AI Servo doesn't specifically address functioning of AI Servo in continuous drive mode. Essentially, the AI Servo will try to maintain focus on the subject, but lack of focus won't prevent the camera taking a picture, unlike when you're in One Shot AF mode.

First, He directly referred to the motor drive, not "Drive Mode". He could have thought of a battery grip as a motor drive. Doesn't really matter.
Second, I have seen Bob be very helpful when a true question is asked.
I have also seen some people just post "rtfm" in response to a VERY simple question. This is not an attack on gyrob, but I don't have a 20d and I knew the answer.
Bob was trying to be polite in telling him to at least look in the manual before posting here.
Look at the number of posts Bob has. This shows that he is dedicated to the forum.

Post count means little to me. The most helpful person in this forum has probably has not even joined it yet. Bob is probably is pretty helpful most of the time, but we can't be so elitist that we only answer questions that are "up to par" or are "worded in the right way" - we should be helpful regardless.
I would hope that any user of this FREE forum would feel FREE to post any question in any format that they like with the expectation that a civil answer would be forthcoming. I don't think that is to much to ask at all.

There is no direct connection between post count and quality of content. I am living proof of that.
As to the issue of questions and answers, I see little wrong with referring a person to the location of the answer instead of just giving it to him (her). To the contrary; that can be very helpful, especially for subsequent questions or clarifications the asker might seek.
Maybe correcting a person on nomenclature is nit-picking, but it is ultimately more helpful if we're all on the same page here. A term like 'motor drive' could be sufficiently confusing to new users as to cause them considerable difficulty in understanding their camera. (What is it? Why don't I have one? Where can I get it?) Not everyone comes to this forum with previous SLR experience.
The forum's policy is to answer a person's question or else say nothing. We call it the "Don't Be a Jerk" rule. See rule #8 here. (http://photography-on-the.net/forum/rules.php)
Indirectly, Bob gave the answer.

I don't have a manual for a 20d or a 20d camera, for that matter.
However, I do try to read all posts if I can and glean a lot of information about all sorts of things. It builds up into a valuable resource over time. Sometimes the manual does clearly state the facts, but not necessarily for every situation.
what makes the whole thing break down, is irrelevant posts like mine – sorry.

To some it apears a degree is needed to even ask a question in here, what on earth is a true question ? and yes i called the Drive a Motor Drive well im very sorry ,my f1n had a motor drive and i thought that it was a motor drive or the same sort of thing in the 20d the 300d and all the rest of the Ds.
i needed help and that is one reason i joined this forum and also to offer help if i can .
Looking at my original post i find it hard to belive anyone in here needs to find fault with it I find that very sad, it was a simple enough question , but as i well know some enjoy playing on words its a game they play .
well if you dont like what i ask or the way i ask it dont reply, go help someone you feel is up to your standard too help .
thank again to the other's .

Rob - your original post was fine - if we were to ban every post that contained a question that could be answered from the manual then half this forum's volume would probably disappear. I also think that posts that direct a person to the answer are fine - as long as they are done with a truly helpful intent rather than more of a scolding nature.

I dont think I made that correlation. I ment exactly what was said. He is dedicated to this forum. I did not say or mean to imply that he was an expert. (Not offense Bob I just dont know you that well.:lol:)
I hope I did not offend ANYONE and try not to in this PC(Politically Correct) world.
I try to live by this.

I don't know if anyone was offended or not. I hope they weren't because most of this is really tongue-in-cheek and offered with the purest of intentions.
I think this thread has served its purpose, however, so I think we'll just leave it here.
Thanks everyone.
