As far as I know, there have been mixed Do's in Europe frequently (Boo-Do in Sitges was mixed with a very gay vibe from what I can tell) but a Gayla that's primarily sponsored by this forum's readers hasn't happened in full blown form yet (ecaarch put together a great London mini-do in late November of 2006) but there has been interest. All that's needed is an organizer, persistence and opportune scheduling. I first wanted to do an NYC Gayla in late '04 after the Philadelphia one - I finally made it happen in June of '07.
