As anyone who visits Drupal.org more then one a year will know, Dries owns the trademark of "Drupal". Dries want this mark to be protected from The Bad People and to be used by The Good People. Since law doesn't really "see" good or bad people but good or bad actions, he had to write a policy on how and when you can use the word Drupal in a service.

For example, you are not allowed to say that you provide "Drupal Certification" programs, but if your company is called ACME, you are allowed to use "ACME Drupal Certification". This makes sense, we are not a MySQL AB or RedHat Inc; we are a passionate Open Source community. So you are encouraged to build your own brand "ACME" and lean on the shoulder of the Open Source giant Drupal, fair enough I think. Mind you: if you spot a "Official Drupal Certification program", you are encouraged to contact the Drupal Association and file a trademark issue. Also note that as an engineer you are probably better of a taring center that does not claim to have "Drupal Certifications".

Some might ask why it took so long to create this policy For those Dries / Kieran created an timeline explaining all steps. My own answer to questions with "when" in it, would have been "done is a four letter word". So if you want to make this policy better by asking question, hinting, dropping suggestions, please point your browser towards http://groups.drupal.org/node/15023 and read the post, the comments, the answers and step if if you think you can add anything to the discussion.
