Any discussion about a skin that is in any way being 'sold' is in effect 'advertising', and we do not allow advertising for any commercial products on these forums.
If you are planning to create skins for profit though, be aware that we won't allow or support them on these forums, as that is not what this Community is about. However, the skins you create with Rainmeter belong to YOU, and you can do anything you want with them.
If you want to take the code, change and add to it or improve it in some way, call it HaroldMeter, and give it away or even sell it, that's entirely fine, as long as HaroldMeter is also open source, you credit Rainmeter for the original code, provide access to your source code, and allow further derivatives of it to be freely made. Mostly you agree not to try to make Rainmeter NOT open source.
Rainmeter is open source, and while few, there are restrictions on what you can do with the source code for Rainmeter.
