There are ways to work around this, but the solutions are not easy. If you have some Netscape 2.0 users, the navigation of frames can be awkward. You need to know to use the right mouse button key to go back a frame. Most users will hit the back button and jump back several pages. Netscape 3.0 and Explorer fix this problem.
Frames makes creating web pages that work, very difficult for the average intranet publisher.
If you want to decentralize web authoring, don't use frames. If you want to limit web development to a few webmasters and these people are prepared to support all authoring- frames is the way to go. We find frames is a nice solution to replicate intRAnet content on your intERnet site. You place the content in the large frame and have different navigation frames for your intra and inter sites. That way you can maintain one set of content files with the same file names and directory structure in each site.
