Hi LvS19, welcome to Psych Central!

If you were connecting from a computer I'd say: click on the "My Profile" link in the blue bar at the top of any Forums page.


You should get a "Your Control Panel" list of links in the left column. You'll probably want the Edit Your Details one first but when you have time, also take a look at the others such as Edit Options.

I'm sorry I'm not familiar enough with mobile interfaces to know how any of that would look on your phone nor to give you any advice on navigating it.
