I've donated in the past. I would be willing to again if activity was at least enough to make the mod playable.
I agree with hooyo that you could possibly use YouTube or another avenue to drum up interest and offer at least a basic understanding of the mechanics, etc. The CS:GO mod is probably a more viable future if you're talking long term. Nothing you guys do will matter if the culture of "LUL UR GARBAGE" persists when new people try to play or people who have been around the mod for years (like myself) are constantly being told they're not good enough. Personally, that's why I stopped trying. I'd love for this to be an active mod that I could play when I get the itch. For reasons stated above, and more, I don't even bother trying.
