Lockerz

So there is this site www.lockerz.com which you can become member from.
And the goal is to answer the daily question (everyday). When you do this you will get PTZ (the Lockerz currency).
You can also get PTZ when you invite people. This makes Lockerz to one of the biggest chain networks on the internet, because you only can become a member of it, when you were invited. So... What are those PTZ for? Well, actually you can buy prices with them. (Price list) And they're just free as sunlight. So if you wanna join? Place a reaction under this post, and you will get your invite soon!
