It's not just a forum primarily based on map-making, but also about chatting around and getting to know everyone. There is also a Arcade which users can play different games to get ranked a number the on the High-Scores.
I realize that people can upload files that may be viruses. So i was thinking that users may only give the unrealsoftware.de URL download, instead of a file sharing site such as Media Fire.

Also, the site was just recently made so expect updates on the forums and such.
