I'm aware that every post has the red '!' that allows it to be reported to a mod.

However, I assume that's for inappropriate content. If for example I'd like a mod to merge a couple of threads to ease access to info, how do I find out a mod for a particular forum.

E.G. The Etihad airlines forum. I don't see how I find who is/are the mod/s for that forum, as it's a forum that doesn't have regular mod activity AFAIK.
