How do I contact a forum supervisor?

Hallo all! Enough is enough, this has been bugging me for a long time! I have become fed up with reading the often incredibly rude, snide, overbearing and sarcastic answers from a regular contributor to the "Photos" forum and wish to make a formal complaint about him, in the hope he might in some way be reprimanded! (For the moment I won´t post his name) These ASC forums are supposed to be friendly, polite places for us Apple users to communicate, and such a person is, IMHO, spoiling the use of the "Photos" forum, answering as he does to very nearly every post.

I speak from personal experience with this person. Surely there are rules about the manner and tone of answers? I appreciate that this is all very subjective, but the "Photos" forum is full of other posters annoyed with his unpleasant manner. I regularly read a lot of ASC forums, and have not come across anyone like this person, who seems to take great delight in rudely putting people down and treating them like idiots. I don´t care how knowledgeable somebody is, but I do expect a modicum of politeness in these forums, as I´m sure we all agree!

So how can I get in touch with some sort of forum supervisor? Thanks for any help! (Sorry for this off subject rant, but this is my "main" forum!) Cheers, Ian.
