Hello, I'm looking for a free IM client that will work for Mac and Windows across the local network so that I can be contacted by others in my business/household without physical interruption. Is there any such IM client out there? Or if there's a way to configure one of the others out there to only work on the LAN that would work too. If you have any other suggestions please let me hear them. Thank you very much for looking. Graeme.
