Some kind of error

is this a plugin? if so, which?

No I don’t currently have any plug-ins running. That is the problem I am having, as to where this is coming from.

but where do you get them? in email? in comments?

Via email. I get anywhere from 60 – 100 everyday.

Every few minutes I will recieve an email with the message “Someone has signed your guestbook!” Thing is I don’t have a guestbook set up. Here is a link to my blog, any and all help is appreciated.

I really don’t think this has anything to do with the wordpress install
contact your host and let them know about this

I will try, thanks.
