Topic: FAQ: Copyright
As I have been getting a few questions about this, I thought it would be a good idea to straighten a few things out. FAQ inspired by a post in the phpBB community forums.
Q: May I remove the copyright from the page footer?
Yes, but please don't. If you must, please try to keep at least "Powered by PunBB" with the link to this site intact.
Q: May I add my own copyright to the page footer?
Yes, but you may not alter the original copyright in such a way that it loses it's original "meaning". It must, in other words, still be absolutely clear who is the copyright holder of PunBB. Adding an additional line with your copyright notice is ok.
Q: May I remove the copyright from the source code?
No. The copyright notice in all the source files must be left intact. Any modification or removal of this copyright is illegal under the terms of the GNU General Public Licence.
