We are going to be upgrading the vBulletin software on Friday morning (0900-1300 GMT) which means that the forum will be closed for a couple of hours during the upgrade process. The update is quite significant and includes lots of new features and a slightly different appearance. The main reason for the upgrade is to maintain security and compatibility with the latest programming languages, apparently remaining on the current version is not an option. I hope you all like the new version and find some useful new features! If anyone spots any bugs or oddities, let me know and I'll try to get it fixed.
