Very nice! Will you leave a comment when you are stopping for the day? Looks like you keep finding more!

Yeah, I think I will stop now...

Sorry, I'll use a different approach next time, e.g., explore use of the "work in progress/draft" feature.

In the language-specific join.html files, there is a code fragment starting with [% i = 0; FOR server = combust.servers_with_urls; %]. It seems that is broken somehow. At least in my browsers, it only shows the introductory "Here are a few servers with traffic/load graphs:" (or respective translated) text, but not the promised/expected graphs.

I don't know how to fix this. If unfixable (e.g., because the backend system has changed and no longer provides the needed data/functionality), it could probably be removed.

No apologies necessary, I really appreciate this!

Ah yeah, the "server_with_urls" thing was a feature where operators could provide links to their server graphs / metrics, but I was worried about spam / junk, so I never made it so users could input the links on their own and whatever links were there were on servers no longer in the pool.

I think we could just remove that feature; it's not clear it's worth bringing back.

Ok. I am working on another PR addressing some further minor nits, will address it there, and push once you have committed the current PR (just so I can better keep track of what is already addressed, and what is still open - and smaller PRs make for better reviewing... - unless you prefer to have further commits added to the current PR).
