Are you able to reproduce the problem in the live demos of RadEditor and especially the Save In Database
demo of the control? Did the rel="me" attribute go away when switching to HTML mode of RadEditor? The submitted content is identical to this one displayed in HTML mode of the editor.
If the problem occurs in DNN only, but not in the live demos, my recommendation is to post your question in the DNN forums. If you are able to reproduce it in the editor's demos, please provide sample content and steps to reproduce it.
