I was planning to write another follow-up post about the new collections extension. Some people had requested links and pictures, and I am more then happy to provide them. However, there's no time for follow-ups now, there is too much exciting news to report.
As of last night, en.Wikibooks has the flaggedrevs extension. We're scrambling to figure it out, get it documented, and figure out how to use it. Plus, we're using a very custom configuration of it, so we're try to evaluate whether we want things changed.
Here's what I do know: It's awesome, with caveats. The flaggedrevs extension seems to interact negatively with new page patrolling, and that's throwing some of our patrollers into a tizzy. It might not make sense to both review and patrol pages (reviewing should suffice), but we have to reconsider some of our existing workflow, and we have to figure out what new flags to give to our patrollers so they can keep working.
Lots has been changing around here in the past few weeks, Wikibooks is barely recognizable anymore. Hopefully when all the dust settles, we're in a much better position then we used to be. With all the changes, now is a very cool time to come down to explore Wikibooks.
