I read some discussions about having a template chooser inside the CB Profiles, or modifying the Joomla template chooser to fit inside and alter the CB Profiles... but couldn't find anything.

I wanted to know how to allow users to fully change the look and feel of a Joomla/CB site a lot like myspace, instead of merely switching between predesigned templates... a way for them to add html formatting or css mods to their editors so that the entire site is changed, and remembered on login.

^__^

There is a Template Change/Choose Module.
But it only changes the Template and you can't do any modifacations.

Awesome, can you link me?

The module is called templatechooser.
I couldn't find it yet but I found a thread about the module and problems with joomla 1.08

So just keep on searching
