I need to downgrade Drupal 7 installation to Drupal 6, how should I handle it? I have pretty much blank Drupal 7 install (w/ bunch of users, which I really don't want to loose), but the module that I need only works on Drupal 6.
* UPDATE *
following is a module that I'd like to use w/ Drupal: Clickbank IPN | drupal.org and as you see developer(s) don't have anything other then d6 release.
Is there a way to export users from D7 and import then to D6?
