@MartinSleziak What about Constructive Feedback?

@user21820 Well, that's basically up to amWhy who created the room. (But it certainly does not belong to room about areas of mathematics.)

I assume amWhy noticed the post about list of chatrooms - after all she is rather active on meta.

But still I mentioned it in that room - just in case.

@MartinSleziak Ah yea I meant as a separate answer. I thought it could do with some publicity. =)
