I always think the best way to make confusion and insecurity dissappear is transparency and information. It doesn't help the case to say "It's the hosting which is so expensive, but that's not even our biggest concern." without going into depth. That sounds like OGA doesn't want anyone to know what's going on behind the scenes and that, of course, makes people sceptical. That is not to defend anyones attitude or social intercourse. Why not make a detailed list of what the costs are exactly made of? Hosting provider, tariff, server specs, traffic statistics, eventual fee-based modules, ... Tell people what the money is used for, in numbers, and keep that list accessible and up to date once a month. :)

OGA is a project surrounding licenses of open culture and often enough open source projects and receives monthly donations worth multiple hundreds of moneys or more. If OGA would be more open and transparent about itself people could actually help alot better. We don't know much about how this website works and OGA always felt like a closed source project. Uploading OGA2 modules, which might not even be used or updated anymore, doesn't really change that. Please don't misunderstand me: I don't think OGA should make everything transparent, just because it receives donations. Of course, donations are not like traditional payments where you can expect something in return. I just think transparency would help with the confusion and give people better possibilities to help out.

I also think a seemingly inactive admin being the one receiving the donations is not helpful, too, even if the donations in fact reach OGA which i don't doubt. The Patreon page looks dead since almost 5 years and Bart seems to not have written anything since years, too. Same goes for the Twitter and Facebook pages, they're all inactive since years. It's good that there are moderators and others keeping the page running in their free time and i'm sure we're all thankful for your work, but a seemingly inactive admin who represents the whole project inevitably raises eyebrows. :)

I would strongly recommend taking the responsibility off of Bart and split it onto multiple people and turning OGA into a collective. True, Bart started OGA but he doesn't have to stay the number one responsible person until the end of all time. Split it up and, who knows, Bart might feel relieved and even become active again. Next, create a Code of Conduct, a concept which is successfuly used in many communities around the world, online and offline, and which even works on GitHub repositories for example, actively speaking out against any form of discrimination and harassment (calling people "stupid" for example is conceptually ableist, always and no matter how it "was meant", plus it's not helpful anyway), encouraging people to be welcoming, respectul and including to make OGA a safe and friendly place and to not have to give multiple warnings anymore if someone behaves bad (which a CoC also defines). Next, look around for friendly and active people and ask them if they want to be moderators, e.g. for the forum, but also for checking spam reports which is a constantly recurring task. Also, a news person writing articles about projects / games using stuff from OGA would be nice, too and could also promote the website to a wider audience if links are exchanged. And revive the social media pages if you want to keep them. I'm not sure if having a dead page isn't worse than having none at all.

These are my thoughts. There's propably more which could be done or i might even be wrong with something, but since we don't know anything we cannot do much - only what you tell us about which, in this case, is Drupal - and which i don't know anything about. So, sorry for a bit off-topic from me, too. :)
