Chat accounts will not work here, however you must use an email that exists in chat to sign up.
Currently I don't see some thing enabled/added. Not sure if you want it this way or not; just thought I'd list a few.
- Editing a post a day/days after posting it.
- Deleting posts.
- Do you get notified if someone quotes (aka replies) to you?
- "Follow" or maybe "friend" certain users' profiles. That way if they post an update on their page or something you get notified (able to turn on/off in settings).
S'all I can think of for now.
