now in signatures...

how do I put something there?

and what do the numbers mean:
for example:
175/150/130

I understand the first number meaning starting weight (maybe)
the second number meaning I have not a clue
and the third, would that be goal weight?

thanks

Quick reply!
The first # is the starting weight, the second is current and the third is goal weight. Now people do get pretty fancy but that's the basic.
