We have nearly a thousand posts with potentially orphaned images with the HTTPS move - folks are trickling these in. We also have had an ongoing project to fix tags that could use some love, or at least a certain temporary lack of restraint.
This is a much bigger project than the past tag cleanup weekend, and yeah, we could/should have planned this earlier. I'll have words in the appropriate place at some point of time
I'd like to propose having this from the 0000 UTC on the 16th of march 2017, running to 2359 UTC on the 23rd of march.
Things we need to do in the meanwhile is probably to update the tag cleanup posts.
If we do go ahead - I'll post a logistics question - (like this)on wednesday and we can move from there
