Hi
yes I agree that the designations are to a degree pointless they do however provide a general idea of if a user is a visitor who returns often and if there are a large number of posts it would be a fairly logical assumption that they have both knowledge and are prepared to share.
Several manufacturers defray their support costs by providing specific users with free copies of software to allow them to help in basic forum questions, in doing so it releases the really clever techies to sort out the difficult ones.
Support is always a cause for discussion and as a user of oodles of software I'd say WA is pretty good for what is essentially free support. Most companies wont support anyhting thats been modified or changed let alone help you to get it to work.
cheers
