I've been keeping track since I first started using Lazarus from Delphi about three weeks ago, and I can report that 78% of all my questions so far (all the usual start-up questions as I bumble around trying to learn everything including the docs) have been answered by using the "search" function of the forum. That's a pretty impressive measure of just how helpful the forums are, I think.
Perhaps a short introduction to the forums would be a good addition to the introductory tutorials?
