If they can't/won't use the Search function or if they never bother to look at the Wiki, I highly doubt they're going to look for a FAQ thread either.
This idea has been on my mind for quite a long time, and I decided that it's not practical. Hence the FAQ thread will be flooded with more questions, because it's always one problem that leads to another or more problems for most of our users. And most of these users cannot really identify or specify what problem they're having.
I'm pretty much neutral about the idea, I don't think a FAQ thread will be a problem, it won't be a great help either.
