Basically, I'm not starting this project without support from members on AB and AR. After all.. what good will this social network be without members? I'm going to need some staff as well. People who will be active.
As for the overall use of the site, instead of hanging around the AB & AR forums, just staring at a shoutbox, you have a full-blown social network to chat on.. with shoutbox.
We are aiming for the people who love freeware and abandonware, want to chat on a social network, but don't want the stupidity if you will.. of Facebook.
