Thanks for the information. It's given me some stuff to think about. Let me address some of these issues you guys gave me.
CSS - we are using a rudimentary CSS style sheet to control the look of the navbar, the color of text and background, and the fonts used on the pages. Can you tell me/refer me to something that will help me learn to use CSS in a more sophisticated way instead of frames.
URL Problem - Yes I agree with that. I understand it can be a problem for some. However, every main page is in the navbar and can be viewed with ease. I don't think it will be such a bad thing to tell people to go to osaradio.org (it's not purchased or hosted yet--that's for later!) and click on the "Personalities" link or whatever page we want them to see. In fact. every page does have a URL, it's just that you have to view that page alone without the frames to see that.
Indexing - Google has found my dad's site, the Alliance and Parents and Teachers site for my school, and my piano teacher's site very well. All of these were designed by my dad using frames. I'm confident that this won't prove to be a huge problem.
Entry Page Problem - Yes. I'm aware of that. That's why every page has a "Home Page" link inside the main content. If a search engine finds this page by itself without the other frames, people have a link to click on to get to the rest of the site.
Maintenance - I'm not so sure I have a problem with that. I'm actually finding this very easy to create. It uploads better then sites I've created with RapidWeaver and iWeb and it takes up so much less space on the servers.
Thanks again.
@vansmith: I'm trying to FTP this to a temporary subdomain for you to look at. My hosting package is free so my pages are being cluttered by large ads. I'll try to find an alternative.
