Thanks for the feedback so far.
We'll leave this running till the next management meeting to get some more.
Obviously this has other implications such as how this will change the dynamics of communication at ImmInst, so members views are welcome on these broader points.
On specifics:
There is a disable button on the upper right hand side, I have made it a bit more visible.
The box could go below the forums or could only be on certain pages, but I leave it up there for now, so it doesn't get missed during the trial period.
There is (limited) remit for a more sophisticated chat feature, but that will have to wait for a few days.
The forum is not broken, it was only being modified for a minute, but I'm glad to hear that the chat is so much fun that few would notice.
Also, I noticed that when the chat box is open, it causes my browser window/page to jump/twitch at a regular rate.
That shouldn't happen with a modern screen size on a fully open browser - anyone else having this problem?
