A ltitle searching of the Knowledge Base:
"FrontPage runs inside the Apache server. Thus, when we enable FrontPage for a domain, everything for that domain must be owned by dhapache (the user that Apache runs as). There is no way around this."
OK, for the clueless this means
1. FrontPage extensions are managed by a different user than your FTP/shell user
2. This means your FTP/shell user is out of the picture.
3. Since the FTP/shell user is out of the picture, no CGI for you (it is not good to run CGI under dhapache, so it is restricted)
Also, since FrontPage runs inside the Apache server, they have to have a different set of servers and need to migrate you from the non-FrontPage servers. This involves changes to your DNS to use those servers, and it takes time for DNS information to propagate from DreamHost to the rest of the world. Same idea as switching from one host to another; like changing your phone number, its quick but then how long does it take to tell everyone you know what the new one is?
