Thank you for the info and the upgrade Mike! I have been running BB3 on my local East Texas Classics club (It's dead, I just keep it up because it is already up). I did some mods for coolness, but I do not recommend the black with white text look. It plays tricks with your eyes!

It is a good upgrade, the Private Message system and user control panels are different, but they are easy enough to navigate, because once you get to the screen, it is somewhat familair.
Thank you for doing this, I know what it takes to do it! Time to ramp up the forum donations guys!!!
