To provide an update, Liam is currently working on a new theme for NEB, which will work without the assistance of some of the plugins we used previously which haven't actually been updated for myBB 1.8 as of yet.

It'd be such a shame to downgrade back to myBB 1.6, after the length of time we've waited for myBB 1.8 to be released, so we'd rather try and fix the issues we have come across with the upgrade.
