'You are not eligible to sell via the trading system.'

Hi guys,

I've gone through Marketplace FAQ/Guide (http://forum.warmane.com/showthread.php?t=174367) and found nothing about prerequisites to sell an item via trade system.
Anyway, I get the following error when I try to create a trade: 'You are not eligible to sell via the trading system.'

Could you clarify what I am doing wrong and extend the FAQ to state this please?

only premium account can sell on Trade ( you need to donate just once to become premium)

Gotcha, thanks.
Would be great to have it ingested to FAQ

Updated the FAQ. Thank you for pointing this out.
