I'd like to personally thank the technical community for coming through on this solution. The ISP community has not reported mass calls to help desks. It really didn't seem too quick and dirty.
I'm a Firefox HTTPS-Everywhere and NoScript kinda guy, and had no problems switching back and forth by turning scripts on and off. Both wikipedia and wikimedia js had to be turned on, though.... Why?
Text-only users will even see the big edit notice on the main page!
Next time, please consider adding a textual edit notice to Special:UserLogin, where the scripts don't load any banner. Perhaps that could be added to the proposed standard extension?
My guess is there will be a next time. ;-)
