I know this is a strange question, but is there a way to let users that are logged in to input a different name and require an e-mail address when adding comments? It's grayed out when you are logged in (I realize this is to keep people from pretending they are someone else). Basically, I'd like to treat them like they are unregistered

The site I'm working on does not really have multiple registered users, except there is one login that is used by many people to access a few hidden/protected pages. So we could potentially have hundreds of comments from that one registered user, when really they are from many different people, and we don't know who.

If not, any ideas on how I might make something work for my situation? My client doesn't want to have multiple individual user accounts at this time.

Thanks for any thoughts on this,
Min
