Quote Chaps the server is going to go through a few tests shortly and I would like to apologise for any inconvenience this may cause. This is being done to track down the problem which caused the crash at the weekend, we are trying to keep the disturbance to a minimum and will keep you posted![/QUOTE]

I appreciate the warning, and it looks like they're trying to do something about it.
