advice needed please

i'm doing my first wedding in august.......its the brother of a friend......i dont have to do any printing,just do any needed efiting and put on a memory card

any advice with techniques would be gratefully accepted

thank you

paid wedding?

what kind of advice are you looking for?

"How do I use my flash?"

"Should I get a second camera?"

"what lenses should I use?"

"should I get things in writing before I shoot?"

Once we know more about what you need, we can help you better.

Vague questions for the looooooooooose.

Can I ask a couple of amatuer questions if you don't mind? I'm in the same boat (1st wedding)...How do you guys make B&G laugh in the pictures? What comments are appropriate to make them smile? I know these questions are stupid but I need your help and advise in that please...
Also, have you ever shot a wedding in community halls where there's no natural light (just fluorecent)? What do I do to make quality pictures?
