Artie's idea is similar to what I just described in the "OS X Forum Sub-divisions" thread for the "virtual sub-forums" I've seen on other sites, in that a poster has to indicate a piece (or several pieces) of information before submitting.
However, if Artie's plan is implemented, will that be required for all posters, rookie or veteran? ...every time you post?
Other sites make use of the Profile to allow members to input their Mac model, OS, etc. That at least provides a clue if the post doesn't spell things out - unless the profile info lists 8 Macs with various configurations!
