Use polyvore. I can teach you and stuff. It's complicated at first. Polyvore is actually better than photobucket as much as I love me some photobucket. :/
I will check out Welcome To the Fall Out. I read a little earlier and I'd like to help :)
Use photobucket. It's the best :D I can make a banner for you. Just PM me with everything you want in it, pictures and all that jazz. Can't help you with the co-author stuff. I get super lazy when it comes to writing stories, thus all my stories have only one chapter. XD
