Sort of. . .I'm going to keep this simple since I don't know how strong your
web development knowledge is, so please forgive me if I sound as if I'm
talking down to you.
FrontPage generates HTML, so any good HTML editor can open, manipulate, and
save a FP generated web page. The problem arises on how much the original
developer relied on FP unique features by using the FrontPage extensions.
As far as I know, no regular HTML editors have the ability to recognize or
interact with these functions, so you couldn't a different editor to create
a FrontPage website. (If there is something new out there, I'm sure someone
will let us know!)
On the other hand, you could use any good editor to open a FP webpage and
convert it to a conventional webpage.
