As a new forum user, I have spent several hours reading. Since I am new to DIY and soldering, this is a BIG jump for me. However, I feel RJ has on more than one occasion advised this was more of a pre co-op as beta was not finished with testing. He stated if there were no major issues with beta, the co op would go forward when testing was over, and if major issues were identified, it would be cancelled. If you don't want to take the chance--don't, another will happen soon enough.
As a Ga mini participant, I saw the wireless in action but because I AM new to this, I need all the time I can get to put it together. My vote is to keep it open (if I'm allowed to vote yet!). RJ has been accountable to his customers and this forum. He has put this forth to be voted on and had his hand spanked, so lets move forward. My order stands--1 transmitter and 3 receivers. Rhonda
