phpBB is what the new version of the MFGG forums runs on, which has numerous improvements over the previous software. Due to enormous backlogs on the Invision forum, previous bans are considered void. The CCC was gone after being supplanted by a less restrictive General Chat for a while, before The Lounge opened in 2010.
For a few days after the opening, both forums were in use simultaneously to ensure there are no problems with the move. Afterward the Invision forum was archived. For a period of one week after the opening, usernames were "protected" by admins, meaning an attempt to claim a username already being used by an existing member can be contested by that member; after that week, that no longer took effect. Badges were reassigned, and some features such as the custom filters are temporarily absent (although those never returned).
The original phpBB board was frequently referred to as "MFGG 3.0," even though this term is inaccurate for many reasons.
This iteration of the forums began November 9, 2009. It was closed on November 15, 2010 while the MFGG staff made drastic changes to the forum's structure. Minus World opened on the same day. The original phpBB forum was archived at http://www.archive.forums.mfgg.net, but the archive was deleted during a server change, and it's believed that the first phpBB archive has been lost permanently (other than the Wayback Machine and any threads that members saved to their own hard drives). Curiously, The Lounge remained open for several months after The Split.
The new phpBB boards were installed directly over the old phpBB boards, so the current boards still contain traces of the old boards (including staff forum topics, warn logs, and old skins like MFGGreece).
As of November 2017, MFGG runs on version 3.0.12 of phpBB. This is a very old version of the software that is no longer officially supported, and because most modern mods and plugins are incompatible with version 3.0.x, it's extremely difficult to add new functionality to the forums. While it is possible to upgrade to version 3.2.x, this would break current themes and mods, so the MFGG administration is working to advance to a superior alternative, MyBB. The phpBB boards are set to close on November 26, 2017.
