The forums were taken down this morning so phpBB could be updated to version 3.0.2. There were some unexpected issues with the upgrade due to certain files modified specially for MapCore being replaced, resulting in those bits lost having to be restored from backups. The process isn't yet complete, however no further problems are anticipated.
