On some outreach events (primarily courses), the newbie limit for saving (8 edits/minute, applied to all newbies from same IP) is blocking normal work ([[ https://cs.wikiversity.org/w/index.php?title=Wikiverzita:Diskusn%C3%AD_prostor_(technika)&oldid=98468#Akce_byla_pozastavena | one example ]]).
We currently have throttle.php (https://phabricator.wikimedia.org/source/mediawiki-config/browse/master/wmf-config/throttle.php). This file can temporarily raise the six account limit, but does not raise editing limit. Thus it leave event organizers to solve this as well, probably by letting the participants wait. This is in strong contrast when compared with "Anyone can edit" slogan. We should either make throttle.php raise editing limits (by one of solutions described below) or create other file working similar to the throttle.php file managing the editing rate limit. In longterm, this should be all managed on wiki, but there is other task for this. This is short-term/mid-term solution.
# A) Set `wgAutoConfirmAge` and `wgAutoConfigmCount` to 0
Everybody editing from that IP would qualify as autoconfirmed user and thus no newbie limits will be applied. This will have side effects like allowing everybody with an account editing from that IP to move/perform other actions restricted to autoconfirmed users. It can make experienced users confused, because non-autoconfirmed user is moving.
# B) Grant autoconfirmed to all registered account editing from that IP.
I'm not sure how this behave. The description of the right ("Not be affected by IP-based rate limits") says to me it is a possible solution, but probably more experienced mediawiki guys should look on this.
# C) Raise `wgRateLimits['newbie']['edit']` and `wgRateLimits['ip']['edit']` for everybody from that IP
This will do just the proposed thing. Still, limits will be counted together for the IP, so theoretically one participant can slow down the other one, but it can work. An example: Event with 10 participants, instructor shows how to edit sandbox and participants do what instructor does. There will be presumably one edit per participant. Then, instructor says "try to make one or two other edits". This will lead to max 3 edits per participants. If we allow numberOfParticipants*3 edits per minute, it should be probably enough for most events.
