Neophytos, I hadn't even thought of this. Unfortunately, the default position in the U.S. is that content, logos, end up being copyrighted unless one explicitly establishes otherwise.
We will put up a "creative commons license" on the dotlrn.org web site, which is similar to GPL and will allow people free and unfettered use of logos and content that appears on the .LRN web site. A good FAQ on the creative commons license can be found at the Harvard WebLogs web site.
