Since I'm not allowed to remove my account, how can I change my display name?

I just tried but don't think you can!

But what is all that about seeing each others email address?

You can search for other people on KDE Identity, including their primary email address. I was also a bit bugged about it in the beginning and agree that a "Do not share email"- option would be nice.

quantdev , if you want to change your forum display name, just send an email to forum-admin@kde.org with your old and new name.
If you want to change your email address associated with your account, you can do so through KDE Identity -> My Account -> Edit email addresses.
If you still want to delete your account, email sysadmin@kde.org to see what they can do.

Thanks Hans, I'll inquire about changing my username/deleting my account. The privacy policies on this site are disappointing. I really should have made more of an effort to check this before signing up.

Please note that it is totally unintended for any email addresses to be leaked (unless you register on Bugzilla, but that has a giant warning before you sign up for it).

Could you please check the "Users can contact me by e-mail" setting in the User Control Panel (on this forum)?
