I like Wobblybob have to admitt I lurked around here for a while before posting any comments.( but I sure as hell did obey all the rules and have never reposted any thing from here which is one of the forums problems)
First I posted comments used the help and support thread and learnt how to use HJ split, I then posted a couple of vids, eventualy started a thead of my own.
I have used several video editing programs that I would never have thought about trying before joining this forum.
When I saw somthing that was wrong I bought it to staffs attention
The point is I have got so much more out of contributing.
I dont think there is any way you can force people to contribute as that will turn peole away, just try and educate them to the benifits of being part of the forum.
