As part of a long term plan to re-invent Four Thirds User, the forum will be updated to vBulletin 5 in the next few days.

Please accept my apologies for any disruption.

We need to bring our server up to the latest software and security standards and the best way to do this is to update both our content management and discussion forum software.

I will post more information on the work and the changes that will be made in due course.

Of course, your feedback is always appreciated.
