This is a community maintained wiki so we encorage users to take action and update articles they deem important rather than waiting for it to be done by others.
And on that note, if it is done by others, the wikis have a "Thanks" extenstion installed (accessible on the "view history" tab of the article) to show gratitude to those users.
That being said, in this particular case, it would be helpful if anyone weighing into the Logistics wiki got involved in the discussion on the "talk" page so it can be coordinated. If no-one's working on something, and someone gets involved, that's great - but if someone's already working on the page and someone else comes along without coordination that can make more work for everyone, and turn people off updating the wiki (it's happened to me in the past). It'd be great for
@him_15 to get into the mix, but only if it's in a coordinated fashion - otherwise it could involve more busywork for both of us. If others started getting involved in an uncoordinated fashion, I'd probably stop updating it, as it becomes orders of magnitude more difficult to get things sorted. Yet another issue with the community-wiki approach, but I'll save my semi-regular "this really isn't an effective way of getting the job done" critique after I've finished updating it (and it's a critique of the system, not of anyone involved outside of whichever person inside Paradox thought it was a good idea to make complex games while leaving the online manual to be outdated at best and useless (the situations for the logistics page until it started being updated, and still the situation for many elements of supply) at worst).
Something like a time-limited tag to say "someone's already looking into this, discuss on the talk page before editing", might be one way to approach it (it could even show who's tagged it)? Then if whoever has ticked that hasn't done anything in X days (a week?) that tag goes away?
On Logistics, trains is now up, and the next section (already partially drafted) to be done will be on conversion after change in control.
