Anyone coming up with a number less than 5 please get my email from a mod, I will gladly book your business. of course it will be post up. And here is how the bonus will work. You send me 500, I'll give you 700. Then you can send me 900 and I will give you 1200. Only catch is you have to know how much your bonus was or you get nothing. Of course there will be a roll over and instead of giving you -110 lines you can have 6/5.
