okay thanks

Answer 1

Yes you can.

You can also answer questions on the RMT even if they have best answer, because yours is a different opinion. All opinion questions in fact can be answered even if they have BA, just so long as you have a different opinion.

It's also worth letting a mod know if you see them in chat, so they can verify and change the best answer if necessary.
