Any site use problems?

I recently received an email from a reader who could not post anonymous comments. Has anyone else experienced this?

I generally accept all comments without any expletives and without any links. The reader assured me that her comments were definitely clean.

If you have had a similar experience this, please let me know (feel free to send me an email if you cannot comment or try and give yourself a screen id by choosing to comment under Name/Url instead. You can use a name only and you can type in Anon into the name section or a screen id of your choice.)
