Escalating privileges system

The administrative burden for running an Alaveteli website is high.

At the same time, a number of features have been discussed which might require some kind of authorisation levels in the website.

A Stack Overflow style system of earned points and privileges seems appropriate -- referenced, for example, in issue #9 and issue #10.

What might the system look like? As a starting point for discussion (points system designed to encourage good quality requests):

Earn points:

• make requests (+1 each for first 5)
• have a request enter a "finished" state (e.g. request successful, unsuccessful) (+3 each)
• have requests voted up (+5 each)
• play categorisation game (+5 for first 50 categorised, none after that)
• have comments voted up (+1 each)

Lose points:

• have requests voted down (-2 each)
• have comments voted down (-1 each)

Privileges:

• 0 points: make one request per day
• 1 point: play the categorisation game
• 5 points: comment on requests
• 10 points: reveal emails when logged in
• 15 points: vote requests and comments up
• 20 points: make up to 20 requests per day
• 30 points: vote requests and comments down
• 50 points: ability to make identical request to multiple bodies
• 100 points: move requests from holding pen
• 200 points: full site sysadmin

Other things we may wish to open up:

• Updating the email address for an authority
• Adding the URL for an authority's publication scheme
• Adding a description for an authority
• Adding a completely new authority
