I use the free Bueno Theme by http://www.woothemes.com/
Am I allowed to change the colors by myself?
Am I allowed to change some things in the PHP code?
Does the information "Designed by Woothemes" has to stay in the footer or am I able to delete it?
If I changed the template a bit, do I have to note this on the page?
I am a very beginner with wordpress but my problem is, that I don't know what my rights are when I have a free template under the GNU license.
