It's kind of crazy that we should be having these kinds of problems 
given how prevalent IM'ing is as a form of communication.

I'm no networking expert but this Port problem sounds a bit like old 
style FTP.  A solution was eventually found using "Passive" FTP.  You'd 
think something could be found for IM -- and in a hurry.

I just can't understand an institution in this day and age -- 
particularly one with a public service function -- that isn't 
_encouraging_ their employees to use IM.

This is one for the history books.
