This sounds like a rather interesting idea. Although, I'm just going to warn you now, ShadowCM, that I can't sprite or map for shit on SRB2. So unless if you're looking for an add-on the quality of flames.wad, House22.wad, heavenlytailschar.wad, or RainbowDashyDash's Honey.wad port, I won't be spriting or mapping if I ever joined this group. Although, I could help when it comes to ideas for wads, or maybe even ideas for the group. I also wouldn't mind judging the sprites and the maps.
I think we should hold the meetings in the Sky Base chat when its installed.
I hope you're not talking about criticism. Because it seems like a LARGE portion of the Sky Base considers criticism "flaming" and the person who's criticizing someone else gets banned for a day.
