It's hard to write a post to not sound like another dull advertisement when you want to recommend something ;). But I really do recommend joining Tigris group to any game developer, and epecially to solo (or small group) game devs as myself.
We - game developers - are pretty rare comparing to other professions. And usually it's hard to find someone with the same interest to talk about game dev, get some valuable feedback of your work etc. Such groups like Tigris dev where you can talk to other guys of the same profession in real time, really help a lot.
So to not make a long post, just wanted to say that I joined this group few weeks ago and clicking that join link was one of the best decision in my game dev adventure. Many people of various interests, using various engines, having different taste, but all very friendly and helpful. Those guys helped me tweak up my curret projet a lot, I mean a LOT. I'm really grateful and having great time with those guys every day now ;)
So jump in guys, we welcome new people every day and it's awesome seeing upcomming projects, WIP of devs and artists before they get it published anywhere :)
