We recently made a change here on meta:
That was based on what we learned from this query in the last post of one of the topics Moin linked a above: Find the users which are more likely to become TL3 - #27 by mcwumbly
Those new “cap” values are likely to become new defaults for all sites in the near future, but we are working through how to roll our site setting defaults through “upcoming changes” in a way that ensures admins are informed in advance and have some control over whether and how they are rolled out to their site, so we can methodically update other site settings more easily in the future.
Curious to hear what settings you end up tweaking for your own site.
