Auctioneer - and most of its friends and relations - are throwing errors on login, never mind when trying to use the AH. I've been to the Norganna Forums, which seem filled with people begging the devs to update, with no response from any of the devs. I'm hoping that someone can say whether or not this will be fixed to basic functionality, even if some things don't quite work correctly.
I've looked around at other AH mods both here and on Curse, and haven't found anything that offers the functionality that Auctioneer does. Obviously, if the authors are not willing to update any more, I'll have to choose one, but I'd rather not if this is going to be updated.
