Remember: It's all just a game. But if you play it right, it's a game of learning, and helping others. That makes it a game worth playing. Experience shows that the great majority in this community are in it for the right reasons.
If you're curious about how many monks there are at each level, have a gander at Number of Monks by Level. :-)
Note: level indicated in the table above is the first (i.e. lowest) level at which the ability pertains, except where noted:
A - Chance of special Initiate_bonus XP for daily login. Eligible to aspire to sainthood. B - Receives an XP bonus for using all available votes. Applies to levels shown only! V - Receives a daily quota of votes to spend. I - Can have a homenode image. Q - Can ask Categorized Questions. M - Can moderate. C - Can consider nodes. K - Eligible for groups in the Cabal, such as SiteDocClan and pmdev. S - Gets listed on Saints in our Book.
This is the amount of additional XP you'll need in order to obtain each level, once having reached the previous level.
Also critically relevant is the Voting/Experience System.
