Welcome, and I am sure that you will find this to be a helpful place.
The moderators occasionally gently remind members to re-read the rules, especially rule 4.9 -- "If you know an answer to a question either answer it or say nothing. Giving newbies blunt answers like "search the forum" is not allowed - please use the typing effort to giving the answer instead. Or just give the link to that post you wished the newbie should have searched for. Respect newbies - you were a newbie once".
A link to an outside source is useful information since it may, otherwise, not be known. On the other hand, the ditto post served no useful purpose and it is understandable that your hackle was raised.
