Wondering who is the best contact for the GPSTeamChallenge website these days?

I'm working on a major revamp of ka72.com right now, and was digging into the internals of the "Post to GPSTC" button. The method documented on the GPSTC website is ... archaic? And I was wondering if it's changed? The main problem is that users are going to get asked to sign in every time they post even if they are already signed in (cookie issue.)

There's a quick fix at GPSTC side (no code, just a web server setting) if the documented methods is still the way to go, but if there's another way to post a session that I don't know about, please let me know too!
