This has got quite bad at the moment. I haven’t been able to search at all for the last couple of days, which means I can’t use “See unread posts” which is how I usually read the board.
Last time I remember this happening (found it by googling on the website) Dannii said that the server probably needed a restart and that only Merk could do it. Which is another reason to try to take the hosting out of poor Merk’s hands!
