Pretty much agree with everything karajorma and Ryan listed, among others. I think the overarching priority here should be to make HLP a place that draws new members in and effectively advertises the amazing work that's being done here. That starts with the main page of the site getting a huge revamp that puts content front-and-center. There was a discussion on Discord about how the total conversions need to be advertised loudly and proudly as Free Honest-to-God Games. Get Discord integrated into the site in a huge way, since it's where much of the everyday chatter takes place now. Get the social media accounts pumping out content on a regular basis, even if it's something as simple as glamour shots. If possible, see if we can find someone with the knowledge to take point on Knossos dev to help push it forward. (And if there is the possibility of finishing up a new forum theme, please tell me it's actually decent on mobile...)
On the staff side, I definitely agree that everyone with some official role in the community should get access to a staff forum, since that makes cross-platform coordination much easier. We need to clearly define everyone's roles, and there needs to be a clean break between the technical and community moderation side of things. As has been stated, we're also desperately in need of some new staff in all roles. As stated in the other thread, I am all in favor of retaining PolDisc, albeit with careful consideration of its guidelines. And the rules as a whole need an overhaul to discourage lawyering and encourage respectful, productive discussion.
...that's not so much, right?
