Indeed, the turnout was lower than expected. Plenty of people showed up, but most only stayed briefly. I think we may either have to aim for smaller sessions until the Steam group is well populated and active, or simply open the server to the public and make it more appealing for random individuals to join (preferred maps, respawn times etc.)
This was an experiment, and while things could have gone better, it wasn't entirely disastrous. We had a blast with the group who showed up and stuck around, and it served as a great learning experience for future events.
Thanks again to those who participated and we hope you'll join us again in the coming weeks.
