Overall, it's very nicely done, IMHO. A few specifics:

Your dodge around facebook's "no more than 10 invites at a time" is clever.

That said, your app has the good fortune of being inherently viral -- users that want to collaborate with friends will invite those friends. As such, I would recommend toning down the requests to users to invite their friends. It comes off as being too pushy (to me).

It's quite plain-looking, which is normal for a word-processing application but out of place for a Facebook application. I would err on the side of fitting in with your context -- add more icons next to functions, etc.

Congrats and good luck!

Thanks for the encouragement!

I just added an icon next to the edit link. I agree it does look plain. I agree that it is too pushy, but until its got self-sustaining growth, they stay there...

It's up to you, obviously, but I found the pushiness extremely off-putting. You need to decide whether the core user activity is writing documents or inviting their friends. If it's writing documents, get rid of the invite clutter. If it's inviting friends, well, good luck, but the app is gone from my profile.

Actually, if you don't mind, want to post your invitation code? (Or email me, [e-mail].) Looks useful :)
