There has been talk about creating a social network for Sandbox somewhat similar to facebook and myspace where users would have their own profile in which they could feature their own screenshots and maps. Also the idea is when someone posts a new map and/or screenshots people would see these updates in a status update. This way users too could have their own Sandbox portfolios so if you're wondering what a friend has been up to in Sandbox you can check their profile. Do you think this would be useful? What features do you think should be a part of it? Feedback welcome

In addition
http://FunFreeGamesHQ.com has been created as a site to host Sandbox games. It is very much a work in progress but it will soon have a Sandbox section. It also features free flash games, tower defense games and free game downloads. If you want your work posted on there please contact us.
Take care!
