Using GroupLens
---------------

   To use GroupLens you must register a pseudonym with your local Better
Bit Bureau (BBB).  At the moment the only better bit in town is at
`http://www.cs.umn.edu/Research/GroupLens/bbb.html'.

   Once you have registered you'll need to set a couple of variables.

`gnus-use-grouplens'
     Setting this variable to a non-`nil' value will make Gnus hook into
     all the relevant GroupLens functions.

`grouplens-pseudonym'
     This variable should be set to the pseudonum you got when
     registering with the Better Bit Bureau.

`grouplens-newsgroups'
     A list of groups that you want to get GroupLens predictions for.

   Thats the minimum of what you need to get up and running with
GroupLens.  Once you've registered, GroupLens will start giving you
scores for articles based on the average of what other people think.
But, to get the real benefit of GroupLens you need to start rating
articles yourself.  Then the scores GroupLens gives you will be
personalized for you, based on how the people you usually agree with
have already rated.
