Do you know if there are any LGBTQ groups for workers in the tech industry? There are some national (eg. http://www.intertechlgbt.com/ ) but I haven't managed to find something with a broad geographical target (eg. European or International). It doesn't have to be an organization, a mailing list or a social media group is sufficient.

If not, is anyone interested on starting something? (Nothing too fancy , I guess a mailing list would be sufficient given a small number of participants).
