yeah, there are some issues with TinyMCE as far as html view but they are TinyMCE issues not mojoPortal issues. There is nothing I can do about them but provide feedback to the TinyMCE guys.
TinyMCE wants to wrap a p around everything and even if I change it in Html view it changes it back, to me this is a bug, html view should allow me to put whatever html I want. I have posted this in their forums before.
As a workaround I suggest use FCKeditor. btw, the next release of mojoPortal will have the new 2.6.5 version of FCKeditor and the 3.0.1 version of CKeditor.
Best,
Joe
