OK, I did figure out how to do this.  Apologize if you get this twice.

myChurch has changed so they are now displaying your real name vs. your alias. This may be the way you had it set up before, however I felt I should contact you to let you know as the current moderator for RCC. I also apologize if there are those of you who I contact who aren't on myChurch. They have also made a couple of other changes to their privacy policy, but this last change came through in such a manner that I personally am not convinced they will honor their privacy policy going forward.

Feel free to pass this along to those you know.

If you feel the need to do something. You can go into your myChurch profile and switch your real name (but if you used a one word name for an alias before, you're now stuck using 2 words). myChurch has said this is OK. If you are no longer using your account you may be better off asking them to delete it. This can be done by sending an e-mail to support@mychurch.org

Also as an FYI, after I feel the word has gotten out, I'm planning on deleting my account.
