Hi. I've contributed to a fair amount of wikis in the past. I recently came across ProleWiki when researching about OGAS and have gone down a rabbit hole with the "random page" button. Although I'm not the most well read Marixst, I see a bunch of places where I'd be able to contribute information & sources.
PS: Just sent some Monero your way for hosting costs. Let me know if you need consultation on server hosting & such, as that's the field I work in (you may be overpaying a bit).
