I don't see the problem here. If a Moderator is seen as "experienced", then why haven't they been promoted to Administrator already? That being said, the gap between Moderator and Administrator is already incredibly slim. From what I can remember, the only difference is the ability to permanently ban and the fact that Moderators cannot target Administrators (correct me if I'm wrong, I'm just speaking from CS:S experience).
Point is, if you give Moderators the ability to perm ban then.. Well, they're pretty much Administrators. This is all assuming Administrators don't have other "perks" to their rank. Might as well just merge the two if it's that big of a deal, because besides the whole "seniority" factor, what else sets them apart?
Way I see it, y'all are making more work for yourself by making another rank when you aren't even considering the simple solution that those "seasoned" Moderators should just be promoted to Administrator if they're so up there :coffee:
