I'm looking for a free internal only IM program, if one exists. At my previous job with HP, we used Jabber, but I don't recall that being free. I have several servers available for "hosting", and the company is 32 people total.
Hmmm...I have that available as a TechNet download. I could give it a whirl and see if I like it before we would consider buying it. We're a small non-profit, so I'm hoping for something free.
