The rules are simple. Imagine this is an ancient setting where you proclaim someone is a minor god. Whoever posts above you, you say they are "The God of X" based on what you know about them. If you don't know them at all, judge based on their avatar/sig/username. 

For example, if Mahz posted above me I'd call him the "God of the Guild" since he made the site, or "God of Mexican Vacations" since he's been on one for 3 years.
