I posted this on another thread, but I think it's relevant to all of the current problems :
I think that the slow service and other little glitchy things are to do with the fact that the Techs are testing uploading images for App users - which is good for them, of course.
But I think it's affecting other areas of the site. I've only noticed this has started happening since the App/images test.
I'm on MacBookPro - Safari.
