I am not able to create, reply, send a direct message, using Microsoft Explorer. I don't see the activity button to the left of my username.
I have gone to Chrome which works but I really don't like. It has become so hard to use the site that I am not on much any more. I had to change my e-mail to get alerts, etc and I am still not happy with that.
I read that others are also having problems. I had hoped that the last update that just happened would fix it but no luck.
