That sounds great to me, I think a seperate place for contemporary styles will sort out a lot of the seeming confusion and resultant argument that we've been seeing.

I have one comment though, I feel that "The place for discussion of various alternative fashions, styles and manners of kilt wearing current today." sounds a little clunky, and the word "alternative" can mean different things to different people.

How about something like;
Non-Traditional Kilt Wear. The place for discussion of the various contemporary styles of kilts and kilt fashion today.
