YOUR CHEAP EXCHANGE IS CONSTANTLY SLOW.  I think when you say upgrading servers you really mean downgrading.  It seems the only thing bulsoni puts time in is making his friends into mods.. . I mean how many mods do you need for one troll box...  

I find myself visiting polo less and less each day.... I suggest you visit Mintpal and Bteer and learn what it takes to be a credible exchange.

Also traders should get an option to cancel a new buy or sell order, but all you get once placing an order is a popup with ONLY "ok" button.  This popup should give the option to cancel and the fact that it doesn't says that ur exchange is preying on peoples typing mistakes... Again look at how credible exchanges do it.
