The forum has been restored from a backup.

We have had a lot of problems with the forum since the upgrade to vBulletin v5.
Because of that the decision was made yesterday to go back to a previous version of vBulletin,
by restoring the forum from the latest backup.

We are now using vBulletin v4 again.
Unfortunately this means that the latests posts are gone,
so if you have posted after 2015-03-28 then you have to post again.
The good news is that the problems are gone, and we have a working forum again.
