Is Yahoo Site Builder actually Microsoft's SharePoint?   It sure looks like it.  I've been working in Sharepoint for a year+ at work.  There is a learning curve, but the site can be designed fairly easily so that others can use it -- ie, other board members could help update things.   Note, however, that in Sharepoint, the rich text editor, the photo editor, and the great drag n drop features -- so you don't need to know coding -- do not work with macs, just with pcs.     Is this the case with yahoo site builder as well?
