You’ll have to pick an identity before the comment can be posted, here are the four options:
1 – If you are a fellow blogger member or have any kind of google account, simple select that box and fill in your blogger id or gmail account; or
2 – Select Name/URL if you want to leave your name and tag back to the website (URL) you are affiliated with; or
3 – If you are a Typepad, WordPress or other OpenId user, by all means enter your id to select this option; or
4 – (and this to me is the simplest!) If it all looks greek to you, simply Select Anonymous!
