Hi! I've got my account set up and ready to mine but it says it's still in alpha in the dashboard?

My computers are:
PC: Intel i7 6-core 3.2 Ghz on Windows 10 and Geforce GTX 980
Mac 1: Macbook Pro 2017  w/ 2.8 Ghz Quad core i7 w/ Radeon Pro 555 with 2GB of GDDR5 memory  
Mac 2: Macbook Pro 2017 w/ 2.9 Ghz Quad core i7 w/ Radeon Pro 560 with 4GB of GDDR5 memory

Browser: Chrome mainly (but have Edge / IE / Brave too).

And an iPhone 6S

Very excited about the project, hoping I was early enough to join in the alpha.
