Our department will be upgrading to GW6.5sp1 in the near future.

Can someone please answer the following questios for me?

1. Does GW Messenger comes with the Groupwise 6.5 product or is it separate product that includes separate licensing?
2. Where do the 'instant messages' get saved/archived?
3. Does it take up space on the post offices or can it be saved to a local or network drive?
4. What format are they saved in? (txt, msg etc)
