Dorothy,
According to this page:
http://www.microsoft.com/office/frontpage/prodinfo/trial.mspx
"How to Upgrade from the Trial Version
When the trial period ends, FrontPage 2003 will go into reduced
functionality mode. You can convert the trial software into perpetual
use without removing or reinstalling software on your computer. Obtain
FrontPage 2003 at any retailer and enter the valid product key when
prompted during setup."
Based on that description, it sounds to me that it should be fully
functional during the 30 day trial.
It's nice to see that if you decide to purchase the software that the
retail key can be used to activate the trial version saving you from
having to uninstall/reinstall, change your settings, etc.
You might want to take a look at the Online Evaluation. You won't have
to buy anything, just install a client which will let you connect to
another computer that has FrontPage installed. Kind of an easy way to
check out the interface, but I don't think you will be able to do "real"
work with it:
