Warmane Trade

So idk if this is the right section for my question but here it goes ..

Got 10 chars on blackrock , recently i put 1 on trade so i made another character so again i have 10 and 1 on trade. So my question is what happens if i dont sell that character in 30 days and i have 10 on the realm?
I checked and saw there arent any barracks for blackrock if im right?

Anyway il proly sell the character since its a really good deal and thats why i made the 10. character but in theory what will happen if i dont sell in 30 days , will i need to delete one of my 10 chars or what?

Not sure abut Barracks, but before that expired character would hang into "limbo", unable to do any actions with it. Until you free up a slot in account, then it automatically appears back. [put another character for sale, exipred character appears back, put it up for sale again and cancel first character to get it back]

Ah nice idea , lovely ty mate
