In process of designing a new look for our Moodle installation; we are also playing with different logos and names for our site. Some of the logos are based on the Moodle logo (). I was wondering if the Moodle logo is covered by GPL or if there is another license or legal framework we should be complying with.
There's a bit in Moodle documentation about usage of the name "Moodle" (trademark) in commercial Moodle services, but we are a tertiary education organization, so that doesn't apply, I think. To be quite exact, our (planned) logo's look (font, color & mortarboard) is copied from moodlelogo.gif and the text is our hostname, which does contain the word "moodle".
