I'm honestly surprised we got as many people as we have so far, we've put 0 effort into any promotion. Occult@Occult has been kind enough to spread the site to his communities and @RandomizedShameFan / Dean was nice enough to promote us on .com, but I don't think we asked them to do that so they did that primarily out of kindness.
Ideally beta testers (OG Vets) would be providing us feedback on minor but also big things, feature requests suggestions but also bug reports, etc., but I think users are primarily focused on content rather than anything else, which makes it hard because content was the least important thing we were focused on at that stage.
Hopefully our Wiki is sat up soon. I'm assuming that's going to be the first "dramatic" feature. I need to get users to test it for me though because it's a bit glitchy. It's also a mess right now.
