What i hope to see in the future is groups. I think it would be a good way to become more social with other players aswell as getting better ideas. By groups i mean a place to chat and show off your creations. There could be a way to accept and decline requests or ways to get in by making a cool creation. I think by adding this to powder toy will make this game spread even bigger than it has already come. Sincerely, TastyCornChips

It's slightly broke, but it'll be the only option for groups until I can revamp TPTAPI's system. @jacksonmj has a browser plug-in that will fix the issues in powdertoy.co.uk's groups system.
Alright sweet thanks for the info.
