Had a few more today that haven't sent the message, but just added me as a friend. I barely notice activity notices due to the amount of these I am doing, so please always remember the message.
If unsure, read the first post in the thread.
Lastly, I do these as regularly as I can, so just be aware that it may take me a few days before I get some Xbox time. I will add all that ask. Oh, and a gentle reminder, not everyone will get in first time, some may not get in at all. I'll do my bit, but then it is up to MS.
If you do get in, I encourage you to provide feedback to MS regarding the system and features. It will help us all enjoy better gaming.
