FWIW, I was going to update to Bukkit to see if I might have a shot at setting up a Creative Day soon by configuring the permissions so Turtle or I don't have to be around to manually assign/unassign the creative mode. This weekend is probably out of the picture (I actually have to be at work on Saturday), but some time next week or the following weekend (Saturday 24th?) should be go for launch!
On a related note, the automatic drop-clearing plugin has long been abandoned and is completely broken with the recent Bukkit builds. So, like I did with WorldWarp,
this evening I wrote a new plugin from scratch.
