Hi, 108, welcome to Wikipedia!  I saw that you posted something on Jimbo's user page.  That's fine!  However, if you're just trying to test out the editing process, we actually have a page set off just for that, at the Sandbox.  You can make test edits there to your heart's content!  Also, there's probably a whole spiel I'm supposed to give you about the benefits registering an account, but I'll skip that; I find that it's a lot more useful to have a registered account, but you don't have to if you don't want.  Anyway, if you have any questions about Wikipedia, you can ask me at , or you can ask the Teahouse, which is a place for new users to ask any questions they have about Wikipedia in a friendly, relaxed atmosphere.  Thanks, and happy editing! )
