There is one with which we are all familiar: John... I'll leave it at that. Most of us know who he is. He has been very busy with a job change and is limited on how often he comes onto this site now.
Other than that, I'm not sure if there are any more.
There are half a dozen Administrators but I am pretty sure that most of the names there are from previous assignments and several are not even with AWS anymore or at least have moved on to other assignments and responsibilities.
He Is In Control, Have a Great Day, Brent
