Hi, first of all sry for my bad english >.<
I saw abaut auction system and coins of luck, u can add money to your acunt and it use for the auction, get COL ingame or move it to paypal.
I suggest to get another extra action to can move ur ingame COL for less money than they cost purcheasing it (like 1/2 of COL priece) to your acount.
For example: if i buy for adena 100 COL i can move them for my account for 5 euros (when the COL priece are 10) then i can use them for use the auction or move it to paypal
If it doesnt destroys the game economy could be a nice method for get items from auction or get some income, what do u think ppl? ^^
