I was thinking that we could make the AG3 forums topics a little like the AG getsatisfaction new topic page. here. I really like the idea of being able to say if it's a problem or an announcement or and idea or a question. Also, I like how you can tag stuff and say how you are feeling and say what it's about (beta, AGI, or a game) Maybe you could do a AG forums powered by getsatisfaction.
Yeah, the new architecture of the AG3 web site will allow us to add more features much more quickly than this version of the web site. I doubt we'd ever need another entire overhaul of the web site like AG3, unless we find some amazing new framework or programming language that makes it even easier/faster.
And yes, we'll be constantly adding new things too. We're already working on a list of features, most of them were user-submitted suggestions, to add to the site once we "launch" the site with the features we planned for the core AG3 site.
