I’ve got a couple open-source projects on Codeplex (I’ll link if someone asks, but otherwise, I’m not quite that shameless ;)), but I’m not really sure how to go about spreading the word or getting people to take notice. Any suggestions for attracting users/contributors?

Blog about them. Release often. If you can, use them in a higher-profile project. Contribute to other projects to build up your reputation. Be very responsive to bugs/feature requests/etc. Keep your issue tracker up to date.
