I have implemented the demo version of chat/messenger for community server 2008.  Things appear to have been deployed OK (no error messages), but all of my contacts appear offline when I know they are online.  Is there a fix for this?  I was planning to roll this out for a client's CS instance, but am now having second thoughts.  Kind of pointless if I you can't IM.

 

Could it have something to do with CS's caching?

 

Thanks in advance for any thoughts/ideas/suggestions.
