It is written for Pub 2007, but if you are using IE7 instead of IE6, then
the directions for using Vista also would apply to Pub 2003. FTP and HTTP
uploading has changed with the introduction of IE7 and Vista.

Given your other post about wanting to sell products, I would suggest that
you use some other program to build your site. Publisher is a DTP that has
limited web building capability. It is intended for relatively simple, small
static sites. What you are proposing is possible with Publisher, but it
sounds like the scope and goals for your site are beyond what you should be
doing with Publisher.

Consider other software that is better suited for dynamic sites. MSFT has
replaced FrontPage with Web Expression, which has a much bigger learning
curve, and given it is in the first version has some issues from what I have
read. you might want to wait and buy the next version. Rob, an Expression
MVP that helps out here can talk to that.

I think I would suggest that you look at the newest version of Serif
WebPlus. From what I have read about it, it has all the functionality you
are seeking built in, and using the program is much like using a DTP...in
other words a much smaller learning curve. Just spend a bit of time looking
at and researching other options before you undertake building the dynamic
site you seem to be describing with Publisher. And read through the last
month's posts in this newsgroup to get an idea of the challenges you will
face if you do decide to use Publisher. Just my 2 cents worth...
