According to Frank Cohen [1], the recently concluded Mulecon attracted 400 delegates (including Mule staff?).. but soon Ross corrects [2] this to say 250, but Dan [3] seems to count only 200+.. erm.. is that including Mule staff?

Anyway check this photo [4] on flickr for a section of this large gathering.. and my favourite "I pity the Mule [5]" :)
