There are two ways to do this. One is for every player to download an override which does it, obviously this option relies on player participation and individuals doing it on their own volition, if such an override was included in the Ravenloft downloads or incorporated into the custom GUI, I can't see it being too much effort, for an obvious reward. I don't think anyone can name any negatives to this being done, other than listing more important priorities, which isn't really an argument against something, more for doing other things first.
The other way as people have noted in this thread is NWNx, which is the linux server version, for some reason I believe it doesn't show the list by default, which as Taty is probably thinking of occurs on Escape from the Underdark: Archipelago, for example. The only issue with this would be that it would require changes on the server end, and I have no idea how complicated this would be for the admins to do.
Would it be possible for the Community Council or DM team to look into this and come back with a ruling or some guidance as to whether or not this is plausible?
