i've been contemplating starting one to ignore, and coming up with a name worth remembering is difficult.
any advice for a good blog site?
I think for us noviceshttp://www.blogger.com
Seems as good as any, free, easy to use and provides a suitable url as well as linking to search engines etc.
At the moment the name we're on is cartoon-hero, but it may change
Yup, blogger is a good site for the novices. They have a relatively great service and feature set that is not too hard for anyone to learn. As to the name how about naming it after one of her short story characters? One thing I also caution is to closely control the email/comment (depending on how old she is). You might want the email to go to you and/or close the comment section (or monitor it).
