OK, tell me again. HOW do I do this?

YIKES! A blog! This means that ANYONE ANYWHERE in the world can read and comment on what I type!!!! They can also tell me (and anyone else who reads my blogs) what they REALLY think of me and I can't do anything about it!!! Or can I? I should probably try to finish figuring this blogger-thing out before I say anymore. I think I'll start now.
