@510: I think the new chat is better and easy to use regardless of device you're browsing from, which is why I switched to it. Can you please sign out and sign back in. Possibly it's just needs to reset your session to work as intended.
Brilliant work! I know personally from working with you here in the past as a fellow admin that you've put a lot of thought and work in to this. Now you can enjoy the fruits of your labour!
The new layout of the actual site is fantastic. Must say I was a bit skeptical about the new chat at first (size issues) but I realized I could change the size of it and it works a lot smoother than the old one.
