does your handle have a number assigned to it?

Not that knowing it will mean anything, but here's how to find it:

First, you must have written a review.  Allowing that you have done so, go to Account Manager or My TER, and click on "my reviews".  There near the top of the review with other stats will be your ID number.

If you are ever busted by LE, just tell them your name, rank and TER ID number.  (Then run like hell.)

But you're right, knowing your ID # is kind of useless.

and that is, you can tell how long a person has been a TER member by the size of the number, the lower number of course being the longer time member.

Of course, that would mean being able to look up other member's ID numbers which would not be possible.
