Click your username in the top right and select "Privacy" from the menu. To hide your birthday, uncheck "Show day and month of birth" and/or "Show year of birth".
Username changes are not commonly granted, but if you have a compelling reason to change your username, reach out to a Mod via PM or by reporting on a post, and include the reason for the request. It will be reviewed and a determination made if a change of name will be made.
In the top right of the webpage, click your username
In the pop-up window, click "Personal Details"
This takes you to a page where you can change a couple things:
"Status" - This is text only visible on your profile, not visible on your posts in the threads.
"Custom Title" - This is the text below your avatar on your posts. The defaults are "New Member", "Member", "Well-known Member". You will also see "Moderator", "Verified Expert", "Verified Insider" etc.
Can I still use Tapatalk, or is there another app I can use?
The new platform is not compatible with Tapatalk or other mobile apps. This platform is designed to adapt to the device being used so you have a similar browsing experience on any device.
Is there still an "ignore thread" or "hide thread" option?
No, there is not an option to ignore or hide a thread. The new platform is based on watching what you are interested in rather than hiding what you aren't interested in.
