I am wondering if anyone has written a bridge with phpBB3? There are a few stand-alone scripts out there that integrate with phpBB3 and not vBulletin, thus I'd like to see if anyone has accomplished this.
If not, I'll see if anyone can take a look at the different scripts and see if they can port them or integrate them with vBulletin separately.
Yes, I'd like to just really share users. There are some mods that no one has converted over to vB that will eventually become crucial to one of my sites. I can deal with the difference in looks/themes/etc, but want it to be easy for my users to use both application sets (vB and phpBB) without needing to register for two accounts.
