It needs to be set to refresh on every visit so you are looking at current data.
~!~ Just a side here... I'm not sure a lot of people realize what a open ended chat board Ihub really is. The above suggestion is a great example... I chose to NOT auto refresh based on my reading and posting habits... I like to come back where I left off on a thread and read everything right up to the present as it gives me a better pulse of the thread.
I just want to say I appreciate the Ihub design where I don't HAVE to auto anything if I don't want to. I hope that part of Ihub never gets tweaked...
