Is there any way to build in functionality, that when a new user registered and goes to post a post, on top of the text entry box there is a "before you ask a help question, have you done..."
And remind them to check for latest updates, or call the service desk and if that is no help, search Geekzone and Google before posting the question.
It would just need to hang around for the first 5 forum posts or so, just a helpful reminder so the respected experts don't have to spend too much of their time off helping people who should first consult the product provider for support.
