I use trello extensively and I think that’s certainly a good idea to have a board there for the coop.
I can think of a couple of things I’ll eventually need help with. Playtesting is one. I’ll need help with grammar and spellchecking and that’s one thing I planned on hiring someone for. I mean, it would involve reading the words cock and ass a hundred times over but hey, the work is there if anyone wants to risk their sanity over it. I’ll need fresh eyes to look over my renders and animations because sometimes you’ve stared at a thing for so long you don’t even see where things clip through each other anymore and stuff like that.
