As title suggests, would it be possible to add sub forum for character sales?
At the moment, I have to spam global chat pretty often with long messages describing characters + titles aren't showing up on armory nor obtained mounts so I'm forced to spam global on character I'm selling because otherwise I cannot provide legit proof of mentioned things.
No. This was discussed by the Moderators and it was agreed there's no real need for that when we have a whole gadget in place for selling the characters, and having such a thing would only encourage people to try selling outside the system, leading to scams and the like. If the Armory has a bug, that bug should be fixed, not a whole Forum section created to make up for some missing details.
