Deleting A User

First, let me say thanks to all the people on here that give up their time – it means that this is my first dumb question!

How do I delete a user from the WP userbase?

See – told you it was dumb! I’ve searched the forum and the codex, but can’t find anything.

It’s not a major problem, but I was playing with my blog this evening and decided I would create a user to see “what happened”. Ok, it created fine, but I like clean and tidy and I just can’t figure out how to remove the user.

TIA!
