It has been like that for a few days now, but I quite miss the alphabetical order. Does anybody know why the sorting system changed and how to set it back to normal?

I sent a support request in and they responded that they will fix it as soon as they can.
In the meantime, the only way I know of is to unselect every forum in your list and then go into to the total list and reselect them in alphabetical order. I think that will work but I haven't had the patience to try it :-)

edit: I just tried it and you have to actually check the forums in the proper order. You can't go up and down the list in haphazard order. It remembers the order that they were checked. Just wait for the fix I guess.
