I have my settings set so I have to approve them before they end up on the site. I mainly do this because I feel better reading the comments before they go on my site. I approve the vast majority of comments.
Anyone can email me at email@example.com , I do not mind at all. Just note that if you want to keep the conversation private or refuse to give out your name to the general public, let me know, because if you don’t, I will assume that you have no problem in making parts of the conversation public.
