If you registered for a YAPC::NA in the past few years through ACT and paid online, you can thank me. I wrote the gateway with TPF's payment processor. On my own time. For free.
I attend Perl Monger meetings, gave lightning talks at YAPC and OSCON, read copiously, expand my skills on the job, take classes, and dispense advice to fellow geeks of any sex. What I don't spend my free time doing is butting heads to establish alpha geekdom on IRC. That might explain why you've never heard of me.
