No more Buffy musical screenings

I only recently heard about the prevalence of these events where a bunch of Buffy fans get together and sing along with the musical episode "Once More, With Feeling." However, apparently Fox has cracked down on these public screenings and there will be no more. It sounds kind of like the old school Rocky Horror Picture Show stuff that used to go on (and maybe still does).

AICN has the news as well as one of the sites (the only one?) that runs these things: http://uncoolkids.com/buffy/

This doesn't really come as a surprise to anyone who knows how the industry works, but this seems like a great idea that has gotten good attendance and Fox could make a decent chunk of change with very little investment by arranging these things themselves... but yeah, probably not going to happen.
