Effective April 18th, we will require that sellers and buyers in the Swap & Sell forums have their full name and email address in your profile.
Email addresses are hidden by default when you register.

Click on "My Profile" at the top of the page, then Personal Profile to add your name to your profile (if you hadn't put it in when you registered).
While in there go to User Options to "unhide" your email address.

**Note: If you have a legitimate reason for not showing your email in your profile, you can show it in your post if you prefer.

There will obviously be a period of time until we have everyone showing this information in their profile, but at some point we will delete posts if you don't show this information.
