links to external conten t- maintaining navigation

Hello listers,

I have a situation where, as a portal-type site, we want to link to many
external resources while maintaining a link back to us. I know that having
external pages load in a new window is out of the question and I know that
frames are to be used sparingly, if at all.

We've set it up so that a link to an external page will load a page called
frame.asp.
(visit: http://www.accessdome.com/law/law.home.asp  and click on one of the
content links for an example). It contains a top frame which holds a file
that is a button back to our site and the bottom frame loads the content of
the external page. The frames are clearly marked via the title attribute.

The problem is that when frame.asp loads in Lynx, it gives you the option to
go to content frame but once you are in the external site, there is no way
back to our site.

So how is this issue handled? How can you maintain navigation back to your
site once the user has clicked on a link to external content?

Thanks in advance for your help,
Michelle Podd
