Convention Listings?

[afstanton]

Does anyone here know of a centralized online location where conventions for RPG's gets listed? (I'm not simply looking for a list of conventions as a response, but a place to check back to from time to time. It would be cool if it had an RSS feed, but that's secondary.)

I felt this was the best section for this question because it's probably most relevant to publishers. If there's a better place for it, please move it.

Thanks in advance!
