Customers will often pay me to setup a website for them which occasionally involves using themes from Themeforest which are GPL Licensed.
1) Reselling
Can I "Resell" the Theme to this customer in the scenario mentioned above? We buy the theme, modify it, set it up on our server (occasionally theres).
I ask because it says:
"You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee." (Which we are not technically transferring) and it says "You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License."
Also, what if the fee were not for "reselling" per se' but for the "setup"?
2) Tracking Changes
The license says "You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change." Has anyone actually done this? If so, can you give me an example of what this looks like?
