Blah blah blah ... this is inside an iframe

below are a bunch of textareas that have class="editor" on them

the parent iframe looks for these and attaches a tinymce instance to each one

You could also modify the code to give different menu's for different textarea's - this may be useful to restrict editing capabilities in certain sections of a cms.. ie: in the header area, you only have access to font options, however in the body area, the full menu gets displayed.
