Hi
I'm currently planning a project, which involves me making punbb somewhat compatible with the facebook/etc platforms, to intergrate as part of my app. 
Punbb seems like the best choice as it's lightweight, and quick.
I did a new install to try it out. However it looks like i'm gonna need to rip out of a bunch of code or otherwise customize it.
Looking at the user table it seems i'll need to remove
password
salt
activate_string
activate_key
email
plus could probaly remove most of the others.
I'm also likely gonna have to rip out the whole registeration/login systems, and auto-log them in via their userid when they view my app.
Is this feasible?
