As stated before, this just gets how long you've been a member here.
Let's say you post once a day, and you have 9001 total posts. (thus having been here for 9001 days)
posts
posts/days
thus
9001
9001/9001
Since the total posts and total days a member are the same, you can easily get 1 on the bottom, but let's pretend it's not that easy and cancel top to bottom.
9001
9001/9001
left with
1
1/9001
=
9001
in conclusion, this thread is richards
