I want to change my signature to something else but don't know how to on mobile. Is it possible to do that?

Update: figured out how to. Click your profile pic at the top of your screen, then press "signature".

Brilliant, birbsRcool, you worked it out way ahead of me! Fabulous that the new version of the site is SO much more user friendly
