Admin is real and Admin does exist. I'm pretty sure if he were to answer every PM or email that he got, he would never have time to do his job or even eat. Even @StnCld316 has trouble getting a hold of him when problems arise.
The software that this board runs on leaves a lot to be desired. The software supplier tries to make fixes for stupid things and ends up creating even bigger problems for the users of the forum. Personally, I would go back to the Simple Machines software. It was both administratively and user friendly. But, I don't pay the bills, I can only offer an opinion.
