I believe the designations for individual members are:
'Newbie' (0-20 posts),
'Jr.Member' (21-100 posts),
'Senior member' (101-500 posts),
'Hero Member' (501 + posts) and
Omnipotent Member (1001+ posts).
Just kidding about the last one.
Hero Member is the highest designation available for 501 or more posts. They are automatically applied (via the messageboard's software program) to an individual member based on the number of posts you have submitted, to date. In other words, based on
quantity, but not necessarily
quality. The designations are intended to acknowledge the poster's contributions to the forums. Most folks don't even notice them but some do. I think it's a worthwhile feature that confers some recognition on those who are diligent and committed to the site and the forums. Nothing wrong with that, even if every single post isn't always a model of edification. Most are worth reading.
