First, just wanted to say I have plenty of those Ludum Dare patches available if anyone wants them: https://ldjam.com/events/ludum-dare/55/the-call-of-qthulhu/iron-on-laptop-bag-patches-for-donations

Second, I was wondering how new users get their invitation code? I have some colleagues who want to join and they're asked to provide an invitation code while signing up. I've been searching but can't find any info.
