Another gripe; unrelated, but since we're piling on...<p>My username ends in a hyphen. Apparently, that's no longer allowed, though my username appears to be grandfathered in.<p>Trying to give feedback about new experimental features lands me on the GitHub communities site, which is treated as a standalone app and thus requires you to log in via GitHub (it doesn't re-use the existing session token).<p>However, Communities won't let me sign up with my username since it has a hanging hyphen, and I can't change the username in the form. So I effectively can't sign up.<p>Support has not responded for over a month. Feels like things are inching toward getting worse with GitHub.
