(Instead of making a new topic I figured I would ask in this one, sorry for the double post)

Is it possible to convert phpbb or invision power board to punbb?I have alot of posts & users & would like to have them moved over (if at all possible).

if it's NOT possible to convert all that, would it be possible to convert the user database? (so they don't have to signup again if it's not absolutly necessary).

this one might be easier then the other,

I was wondering if it would be possible to link offsite for an avatar? I would like users to be able to use avatars but if my forum becomes big I would like to lose as little bandwidth as possible (which is why I LOVE Punbb)

the second one would be more like, I would like to have subforums but on a different location like say have the main forums at /forums/index.php then a second forum at /forum2/index.php but the userbase would be the same so people wouldn't have to signup for a bunch of different places.
