If you want to remove the credit link, that’s fine. However, I would massively appreciate it if you left it in, as giving credit is a nice courtesy and that’s how I get a lot of my business. 🙂
Instead of removing it, I would suggest that you sign up for my affiliate programme. I can then walk you through how to swap out the normal link for your affiliate URL, and then you can start earning money through sales generated via that link!
