Thank you, Riot

I logged in to day getting ready to play with my favorite league streamer, and discovered I was invited to the [Alpha Client].(http://i.imgur.com/dW9WxBO.png) Seems normal, right? The thing is, I dont recall ever signing up, this speaks volumes to me. I deeply appreciate being invited even though it might not seem like a huge deal. Thank you for reaching to me, Riot Games.
