It is definitely taking longer to make progress then I had hoped, but I do think the participants here already have helped build a resource the likes of which have not been available for a very long time. And we have taken steps to identify a core of people who are not content to define their goal in life as a pseudonym for nothingness.
I think most of us here already can articulate that vision in core terms that are sufficient for our day to day use, even while we enjoy pursuing further details.
As I see it, this is the "base camp" for the "strain" of Epicurean Philosophy you're promoting. I use "strain", because, [apparently to me] like it or not, this is an alternate path from the popular consensus, and from the academy; this comes from my yet-very-poor knowledge about this "strain". But if I were wrong (and I've already found the thread about Epicurean documents - from Charles - that makes me think that perhaps I am), this could be the "base camp of Classical Epicurean Philosophy", and an effort would be worth it to promote it as such, and also to keep the quality and level of posting around here "high" (as it seems to me you're doing already).
so the issue is how to find and connect with those, who aren't necessarily going to be found on Facebook or Reddit or Twitter, or hanging out in philosophy interest groups (the last of which is possibly the most toxic of all, as it appeals to eclecticism and skepticism).
From the basis of what I said lines above, I would suggest exploring the possibility to create a "wiki-style" section of the platform, where users with the right privileges would write and edit the resources put there, and that could be accesible from the outside as the go-to place of everything Classical Epicureanism. This wiki would allow to keep the forum focused on conversations, and have a separate side for definitions and reference to resources. Easier said than done, I would guess. But I've seen it applied to many different groups of interest throughout the internet, so perhaps it is feasible. One of the advantages of it is that you could keep this forum closed from the search engines to allow for the privacy need for quality discussion and conversations, and have the wiki with all the accepted definitions open to anyone with access to a search engine; and when somebody looks for something they've heard about, they would come up with the wiki, instead of another source of the academic consensus that could get them confused.
