I thought that is what Lotus Domino was for and both could be hosted on the same server...?

That's a good point. In the 2005-2007 time period, there were tons of comparisons between SharePoint and Domino. But I think those two are going off in separate directions. I'm not a SharePoint fanatic....there are many things I wished would work differently, but god, I hated having to work with Lotus!!!
