hmmm license on the letters used depends on the font you're using for the letters I think? but you could probably make your own letters :) Maybe use a font that's a bit easier to read? If you want to copyright your own work, just put a copyright mark on it and you're done. To copyright text or such you could sent it to yourself in a closed envelope and have it so that the recepient (which would be yourself) has to sign in order to be able to accept the mail. Then leave the envelope closed. That's how it works overhere anyways. It's a little vague though... Also, since this stuff is for school, I think that in the papers that were signed to get you on that school of yours there may very well have been a clause which states that the school has the exploitation rights on everything you make for school. In which case you might not be able to prevent the school from exploiting your work.
