Lol, I love that 'Tavern Generator'. I just used it on the random setting and got 'The Massacred', a tavern run by a female half-orc aristocrat, lol. I never knew WotC had those things on their site; I really wish they'd reorganize that site so that it's easier and less painful to navigate.
Although this doesn't suit the original posters enquiry, for those who don't know, psionics.net (the chat network where the chat channel for this board is) have two bots which you can summon to a channel (as long as you're the channel owner/operator) via the /invite command. I don't know what it is about those dicebots, but I love them and created a room especially so that I could use one for my PBP

There's even a room (#Open Gaming) where you can go just to roll a few dice.
As a side-note, if you use it, consider donating to the runner of the server, bynw, to help the server going (hey! I would if I could but I can't even afford salt for my rice these days!) as he's provided a cool gaming-based chat server for the benefit of the gaming community for years now and deserves something in return.
