Imma just quote Emily's thing on this, it's easier xD.
To answer your question, however, there are posting ranks (Outside the FAYZ to Little Pete) and moderation ranks which cannot be achieved by means of posting.
I'll start at moderation ranks, since I'll have to go and find the posting numbers for the posting ranks sooner or later. xD You have Adminstrator through to Mini-Mods. Keep in mind these positions can't be 'earned' as the other ranks can be.
Administrators are of the highest authority within the forum - they help to maintain everything techie and maintain all the special things which keeps a forum running.
They also like to make perverted jokes. Their usernames are dark red on the forum and have the rank 'Administrator'.
The next highest authority are the global moderators. They do more direct modding and still contribute to what the adminsitrators do despite the fact they are moving, locking threads etc etc. Their usernames are a light green and they have the rank 'FAYZ Council Leader'.
The next down from global mods are just moderators (not said bluntly; I love you Sunny, Julia, Jeremy and Jiffy <3) and they do direct modding as well and once again help the administrators in maintaining the forum. Their usernames are a dark blue and they have the rank 'FAYZ Council Member'.
The next down are mini-mods and there are currently three different types of them. They are the Librarian (Merwin), the RPG moderators (The Queen of Spades and McCann Can Triple) and the chat moderations (The Iron Rose and myself). The roles of the mini-mods are pretty straight forward and their usernames are all the aqua-purply you see my username as. Their rank titles are different depending on their job.
(There is a full list here of all the staff (although it doesn't include Sara and myself because we don't moderate the actual
forum:
memberlist.php?mode=leaders )
Now... onto posting ranks! (I've got and searched for the quote now >>)

Outside the FAYZ (0 posts and over)
Human Crew (10 posts and over)
One Bar Moof (25 posts and over)
Two Bar Moof (150 posts and over)
Three Bar Moof (300 posts and over)
Four Bar Moof (600 posts and over)
Five Bar Moof (1200 posts and over)
Super Moof (rank = 2000 posts and over, color = 5000 posts and over)
Little Pete (10000 posts and over)
You'll get the updated rank + bar once the hid the designated number. Keep in mind the Super Moof colour at 5000 and the Little Pete colour at 10 000 has to be applied manually by the admins and doesn't come the second you hit your number.
Profoundly blunt edit: The Durdel rank is contest winners and their usernames are yellow with a GIF 'Durdel' rank.
I hope this helps and wasn't too rambly - if you need to or want to know anything else feel free to ask :)
