Surprisingly I don't think UBBDev hacks that much of the UBB... The only thing I can see from my end is the Calendar, MyStyle, LK's Time Zone hack and a couple of other things...
Donate to UBBDev today to help aid in Operational, Server and Script Maintenance, and Development costs.
Please also see our parent organization VNC Web Services if you're in the need of a new UBB.threads Install or Upgrade, Site/Server Migrations, or Security and Coding Services.
