Wikipedia friends: what’s the best documentation on doing editathons with mostly-newbs these days? e.g., best practices on account creation, edit tracking, topic selection?

And also any good reading on frequent newb-toe-stubbing? (like, is VE finally on by default for new accounts?)

(I mostly dislike the fediverse “please boost for visibility” but if someone on wikis.world wants to boost this into that stream/community I would appreciate it!)
Related question: is there a way to query for {{CN}} in a given category? like, I’d love to be able to give people a list of {{cn}}s in https://en.wikipedia.org/wiki/Category:Open_source

@luis_in_brief I think you should be able to do this with quarry? You'd need a SQL query with categorylinks, templatelinks and page tables, I guess? The recursive nature of the category is annoying though.
@luis_in_brief Actually, ignore that. It's easier. You can just take the intersection with its tracking category https://en.wikipedia.org/wiki/Category:All_articles_with_unsourced_statements (which allows you to also catch all other templates with same function). Of course @magnusmanske built a tool for that! PetScan. https://petscan.wmflabs.org/ For some reason it's very slow right now, so my query isn't returning anything.

@luis_in_brief There's also "WikiProject Cleanup Listings" - check the "by cat" links for examples, at https://bambots.brucemyers.com/cwb/index.html -- It's updated every Tuesday, and I just added the https://en.wikipedia.org/wiki/Wikipedia:FLOSS task force to the list so it will show up there in a few days.
