As kero pointed out my post on MSE - Testing three-vote close and reopen on 13 network sites (it's linked in the featured on meta sidebar) - we've finally got this project under way and WordPress is one of the sites we'll be running the test on.
Starting tomorrow, I'll be changing the site setting and closing and reopening will require only three votes. This test will run for 45 days and will be turned back to five votes to close and reopen while I review the data from the 13 sites. After we've seen the impact, I'll be posting results and, if there aren't negative impacts, we will change the setting to three permanently.
A few weeks into this, I'll be posting a question here on meta to ask for your thoughts about this change, so you will have an opportunity to discuss the impact.
Thank you so much for your patience while we got this prioritized and scheduled. There's a lot more information in the MSE post, so please review it.
