OH MY GOD! excuse me while I go and squee over the possibility of a collab...
um... anyways I love the idea of doing a fic/art collab though I don't think we should be choosing our own partners. Mostly cause there are people new to fandom and they might feel left out or everyone wanting to choose the same people etc. well, there is also my own insecurities and I'm sure it's shared by others that I won't be able to find a partner cause no one wants to work with me. So best to just pair us up.
Oh and I picked 2 month for the time but if it's a collab that's probably the minimum time we would need. I would like to suggest that we start posting in the beginning of September and give us all summer(3 month) to work on it. I am of course saying this in the perspective of an uni student and will there for have the most time to do such a huge project.
