If you are interested in supporting me and my work, here are two options:
First of all: Using TabStats is for free. You don't have to pay me anything. Nonetheless the server for TabStats isn't zero-priced. So if you'd like to support me, feel free to donate me some money. I'd use it wisely.
I pursue the same hobby like (probably) all of you: I love playing Counter-Strike: Global Offensive. It's my passion. So if you'd like to support me/thank me for my development of TabStats, feel free to send me gifts via my trade link.
