Apologies in advance if I've forgotten how this works, as it might not be a bug but a misunderstanding/oversight on my part.
I can't seem to change my banner/header image on my profile like others can. How do I do this, am I missing something very direct? I feel like I've looked everywhere. Thanks!
Note: Had a GB account long ago, but couldn't remember it -- so this is a new one for my subscription.
