I agree when they say it's the mods job but trust me, I've seen the mods not do their job. I'm not bashing anyone, because trust me the mods are doing a fantastic job right now. I'm just saying, not all of them are perfect or always are doing things right. And also maybe staff wants someone to be recognized as someone who is actively supporting others and all, but they don't trust them to give them powers or even have enough room.
I wouldn't be against a rank like this, but I don't know how many people would be suitable for the rank. (if any)
Oh, and yes, there was a rank like this before that I had for a short period before it was removed. First it was a light greenish name and a pip that said "Client Support" , then just the pip, then the rank was removed all together.
