Hi Rick,
You can use GreyBoxHyperlink to open a dialog page with an editor on it. I did this recently in my Form Wizard Pro product to support an instruction block question type so additional instructions could be placed among the questions. Since the editors don't work inside an UpdatePanel I created a dialog page.
For something kind of similar in mojoPortal, look at the way the help links work. They open a greybox dialog with the help text page, but for admins it also has a link for an editor. In your case you would just have the editor on the initial page opened with the link.
Hope it helps,
Joe
