I have to say that my personal experience at YAPCs and perl workshops is very good; I even was member of the orga team for the first time recently. We added a short policy against discrimination and harassment to our call for participation. I would like to encourage you to participate in conferences, and in case of an issue, talk to the orga team or the person in question; maybe that's the best way to make the right people aware of the problem. =)
Re^5: How many man-hours would you estimate you have invested in learning Perl?
