Since the start of this week the forum team has been viewing the forum using a new method, where they see each post as it is created rather than the standard forum view. For example this is how they'd see the 100Mb Forum.
What this means is that you shouldn't have to worry about new posts in a thread knocking it to the "back of the queue" any more. It also means that 'bumping' threads will still not work as a method to attract the forum team's attention.
Just to be clear we still want to work with the forum community to help answer your questions here, but what we say on the front of the forum remains true. We're still going to do our very best to help in situations where the forum community can't, but we can't promise a quick fix so if you've got an urgent problem we'd still urge you to contact us directly. We're hopeful though that this change will help things run a bit smoother here from now on.
