Although I don't really care about what happens about this, I will say this:
There is a difference between a moderator and an admin, if you make it that way, I have experienced this. When I have been admin on other servers, I have all the powers, such as being able to ban players for much more than an hour, etc. Compared to where I have been moderator, you get all the minor commands such as muting, kicking and banning for short times, however you aren't able to ban for more than an hour, mainly because the moderators were meant to hold the fort until an admin could come and clean up the mess completely. The moderators were simply moderators because, even though they were trusted enough to have power, they weren't trusted enough to have a lot of it. So basically it was like testing to see if someone was trustworthy, and just overall good enough to be an admin (unless they wanted to stay as a moderator.)
I don't think it's necessary to have moderators, I think the admins do a great job, so I'm not supporting getting them. I am just making a point.
