Okay, here goes:
Post-count-based ranks:
Scouting Stranger, Farm Hand, Villager, Citizen (in the original sense, i.e., someone living in a city),
Capital Dweller. To be extended as counts rise, and the protagonists discover new, ever-more-interesting locations.
(Keep posting now, and you can become a Ruler of the Derelict Airport!)
Special ranks (I'm listing more specials than the forum software AFAIK supports, just in case):
Minced Troll - banned permanently
In Quarantine - banned temporarily
Fallen Caster - a user whose posts will only be published after a mod proofread them (presumably due to persistent use of strong runo, er, language
)
Cleanser of the Scroll - forum mods
Lady of the Budget - forum admin (yes, that means
you, Eich. You
are getting billed for this server, aren't you?
)
Snout of the Giant - anyone whose big-mouthing has incurred the wrath of her Ladyship :'(
Aurora Officialis - Minna herself
I'm intentionally staying away from single words straight from the comic (e.g., "Troll") because they're usually part of a series (Beast/Troll/Giant/...) that we might want to use
as a series later on.
