Today I tried to post my first technical question on this bulletin board. But all I get when I click the concluding “Add topic” is an odd error message stating
Sorry you cannot post a link to that host.
The only link I could see in my entire post was a link to my own repository on Gitlab. And even when I edited that one so it no longer looks like an HTTP link, I still get the message. What exactly is prohibited here? Or is it just a bug?
