Finding an Intercambio

Hola a todos!
Does anyone out there know where and how to set up an intercambio? The e-board at Asatej travel agency, that someone here previously recommended, is disabled. Are there other places (travel agencies, UBA faculties, etc) where people commonly post for intercambios? Thanks, I'd love to do an intercambio here but I don't want to post my info in random places without hope of success or, worse, sketchy respondents.
Cheers, Annie
Talkarama and the English Group meet once a week and have many of locals who want to improve their english. You can find a language exchange partner there.
