Ok, store idea = good
Membership fee = bad

I love this site but I won't pay to use it. It's not the only Flash resource on the net (although it is the best), and I won't pay for something I can get elsewhere for free.
I'm sure this didn't need to be said as I'm sure you realize how many people would be chased off by a fee.

Finally, the reason I'm posting is to suggest a feature in which you can search through a select number of forums, instead of the current "one or all" method. To be more clear, give me the option to search through say, Flash 4 Actionscript and General Help or what ever combination of forums I choose.
