We'll take the forum offline at around 2pm. Backups will need to be made, and will prolong the time the task will take. Server should be back up by 7pm although we hope it will actually be done and dusted sooner than that.
In coming weeks various updates to vBulletin will be installed. Downtimes will be advised.
In the meantime make sure to register for the back-up board at http://followfollow.proboards86.com
