Thank you for the link. It does clarify a few things from the previous link they posted which is why they posted again to explain.
Also just to clarify a point if I may. I took from your statement that the insider program was a time bomb, which it isn't. True you have to update to continue but that is not a reason to label it a time bomb which has been associated with a program that was going away. Just a terminology that can be misunderstood.
Also as Lou states you can not join the insider at the moment but they will allow you to join shortly. The insider program was in all intents for expert users and released to the general public in an attempt ( IMHO ) to appease user that were sorely disappointed with the entire Windows 8 experience.
So now we all agree and its time to move on. Thank you again.
