Thank you I appreciate it :) I sent two messages earlier but I have not received a response. I would hate for someone to come across one of my posts. Especially since I spaced on the fact the user name I used I also use for other things.
The terms of service say it is not possible delete posts. But you might try communicating with the moderators, I have seen them delete one or two posters for bad behavior, and once they did it when a woman had written in for advice but then felt it identified her so much that she was unsafe. I believe a poster can take on a new user name, but it does not change all their back posts to the new user name. I'll drop a line to the moderators on your behalf and in hopes they can tell you whether this request is possible.
