Thanks, great answer.
So, in my case, where there's only going to be one kind of user - administrator - can I just poke this into the <CE:Editor ... > tag something like:
<CE:Editor id="ceContent" AutoConfigure="Full" SecurityPolicyFile = "Admin.config" UploadsFolder="~/Uploads/" ... etc. />
<thinks>
In fact, the uploads folder is already in the Admin.config file so I won't need that ... things just get better and better.
</thinks>
Thanks again
