1) I'm at situation where I have logged in, and can post new threads, but those thread I visited before I logged in won't recognize the login, so I cannot reply to them.

2) This new forum software so much worse than old (within 30 minutes of usage I have found few bugs/ux issues), is there a certain channel we should use to report bugs and issues we find?

System: Mac, Os X 10.11.6, Firefox 51.0.1 (64 bit)
