You really should search the forum for the problems before reposting.

I found you more fit for that. If by any chance a same question is posted by two or more independent sources, then each source would have a different crew of persons answering that, those who remember that they have already gone through it, would definitely like to skip that, instead of wasting time in searching and posting one more source that has posted and discussed the same problem with a different crew of persons. I don't think that reposting by any chance is any offence, neither we should look for all previous posts before posting one question from our collection. This is absolutely impractical for those who have more than one reason to visit such forums. Keep doing the great work, man!
