I found location to be helpful- think about it- when a newbie found they other site- they had a 50/50 chance of posting where they were from- sometimes they put it in an intro, but then- 6 months later- they go to sell a part off their sling, and you have no flipping' clue what shipping is going to cost, 'cuz you have no location.....
birthday cal nice, if only to harass
don't care about age, 'cuz I'm perpetually 29......
