Track your blogs!!!!

Hey everyone, I am a little concerned with this whole blogging thing! Even though I am a private blog I have some one that I do not know from Provo that has been getting on to my blog, his site is not very nice, I don't know how other then he has someone account information!?! I really think everyone should put a tracker on their blogs to see who and what is going on with their blogs as he is leaving mine through many of yours!!! I got my tracker through sitemeter.com It sucks that one person can ruin this for me but unless I can find out who this guy is I am done blogging, so who ever you are buck up and leave me a comment.
