Ha! Good one… I log in from play.eyewire.org… FireFox (15.0.1 Mac OS 10.8) working REALLY WELL, fast and smooth! Not tried Safari yet
I’m glad it’s fast 
I’ll try to figure out why you can’t get on chat.
A lot of the new features I’m developing rely on the same technology driving our chat, so it’s important for me to make sure the chat works for everyone.
I’m curious if you can use the chat function now. Can you try signing out and signing back in? Are you able to write a message in the dark grey text-field to the bottom left of the page, hit enter, and see it appear?
Thanks
