I have been reading older posts regarding wordpress licence. It's not clear to me how it works. Please answer a few question and help me understand the extent of wordpress licence.
1) If I make a site for a paying customer using WordPress am I "required" to give the client the source code?
2) Would the client own the code? Or will the site's code belong to the public?
3) Am I allowed to modify WordPress and put my own logo in the admin sections?
