Sooo... Apparently all the mods always thought that we got an extra point. Turns out we don't. But, on the other hand, everyone does get 1 point for simply joining. Turns out
we actually found this out two year ago and all promptly forgot.
You may have received rep from a new member that gave you 0 extra rep. That's because the rep power doesn't kick in until they reach 50 posts.
So, the actual calculation is as follows:
1 point for joining
1 point for each year the person has been a member.
1 point for each 1000 posts.
1 point for each 500 rep points.
