Hi Alex,

just discovered by chance that my profile in mlf2 is indexed by Google. This is not a good idea...
It's not possible prevent indexing in a robot.txt as it was in v1.x:

  User-agent: *
  Disallow: /contact.php
  Disallow: /user.php

Robot.txt calls for correct (complete) URIs; both lines below

  User-agent: *
  Disallow: /index.php?mode=user&show_user
  Disallow: /index.php?mode=user&show_user=

will not work.

Therefore another method must be applied.
At least all links to 'index.php?mode=user' must be extended by rel ="nofollow". It's quite common in other forums and also standard in Wikipedia to use this method for all external links too.
