Hi,
I get amazed every time whenever I find a new subdomain under google.com because each and every subdomain has tons of different things to offer.
This hit me, and I decided to find out how many are there. So I started compiling and after a month of tracking, the list crossed 100 websites. These 100 websites have covered almost everything you need, doesn't matter from which profession or community you belong.
You can be a student, businessman, entrepreneur, single parent, or anything. You will be helped.
You can download the whole list for just 2$. Check here. https://www.buymeacoffee.com/Aarvy/e/4457
