I finally got around to upgrading the official BZFlag forum to phpBB 3. Had a few quirks, mainly with the authentication for the game clients/servers. The new version of phpBB uses the utf8_bin collition, which is case sensitive. Had to use a bit of code from phpBB to convert a username to a ‘clean’ username, and then compare that to the ‘username_clean’ column instead of the ‘username’ column. Groups also had the same issue (case sensitive comparisons via the queries), so I just made all of them uppercase in the database. Hopefully that’s the last of the major issues.
