Why Don’t You Post Your System on Your Profile?

Forgive my ignorance- but- how can I post my system details in my profile? I've tried to figure out how to do it and it eludes me. Happy to do it if someone can tell me how ? 

thanks 

Thanks, when I click it takes me to the right place yet when I hit create system it says user can't be blank- even though it shows me as signed in?

THat's what I get, then i name it, I'm signed it and it then shows. a red bar and  "user name can't be blank". Same thing another member is getting regardless of browser. 

@toddsyr same results for me, logged in with safari and tried it. got the same red bar even though I'm logged in and named my system. Not worth the continued efforts and posts about it. You'd think that after all these years Agon would have a functional and friendly site....
