Your message on the front page of the site did not give any forwarding address for you. If you sign in, as suggested in Cowantex's message above, then when your e-mail address is registered with the site it will be private but you will be able to get e-mail messages from other users of the site without their knowing your address. Just click on the "Please sign in and create a user name" link in her message.
If you have questions, you might try using the help desk.
1. You can send an email to cowantex to activate your listing.
2. The wiki is a workaround for the original site. Doc is working on bringing up the original site. (Doc's site went down Oct 2011.) When I created the wiki, it was from "snapshots" from the Way Back Machine ... thus, any volunteer information such as emails was not available from the snapshots.
