Allow friends to see your email address in the PTC Community
While the PTC community features a direct messaging feature, you may want to share your email address with your community friends so that can contact you outside of the community. You can do this by following these steps:
Navigate to My Settings by clicking your avatar icon at the top-right of the screen on any community page.
Now, select the Preferences tab, and then Privacy:
On this page, you can allow Friends to see your private profile information, your email address, or online status.
Click Save to save any modifications you made to your preferences.
