auto-create blog post upon registration?

Hi!

I realize this isn't core functionality, but if anyone could point me in the right direction that would be awesome. I would like to auto-create a first blog post for new easy blog users upon registration, so that when they first login, they already have a draft post they can view, edit and publish. I know there is a login redirect function, but is there any similar functionality upon registration? A custom php solution would be fine too, I'm just exploring the options for know.
BTW - users register through easy social, if that makes any difference.

Thanks!
