I’ve heard people are having problems leaving comments. Apparently blogger [owned by Google?] requires people to sign in to leave a comment.
Beneath the 'Post a Comment' box is the 'Comment as' drop down menu. If you have a gmail [Google Mail] account select Google Account from this drop down list and use your sign in info. The same goes for the other choices [some of which I don’t recognize; what is an AIM or an OpenID? Is there a OpenEGO? Guess I oughta google ‘em]
If you don’t have a gmail account you might want to get one - it’s free email that you can access from any internet connected system [very handy when you’re away from home] and it allows you to post comments on cool blogs - like mine ;p
