Extra users!

[Sharon Kimble]

I'm using Fedora Core 2 with kde 3.3.0-1.0.2.kde and my gkrellm process 
monitor is showing four users, except that this is a stand-alone and not 
connected to any network [except the internet], and I'm the only user.

So how do I find out what these other processes are, and then how do I kill 
them please?

Sharon.
