I'm afraid it's more than just some of the forums that are having difficulties.
Along with quite a few other things, the online counter is broken as well. There aren't really 18 online. The members online page just isn't refreshing. Those who leave aren't being accounted for very often, and this is the result. We won't really have 18 online until Xmas.
I can't even post the homepage article. That's broken as well. The outage yesterday afternoon didn't help either. Wayne explained the situation. It's all just going to have to wait for a bit.
