It's becoming too difficult to DM every new forum member who joins, so I'm gonna post this here:
There's a quirk with the AF website in which the URL field on your personal member page may display the first half of your email address. This is an issue if the email address you used to create a profile has your full or partial name in it. In any case, your identity and full email address are completely protected and remain unknown to any of the forum moderators and fellow members.
To check this, and to change the URL to whatever you want (if you want to remain 100% anonymous), take the following steps:
Go to My Account
Go to My Community URL
change URL field
save and then refresh your page to make sure the URL has been edited
Most people have done this already, and others are clearly fine with using their real names here in the forum. If you have further questions, send me a DM.
