When you ask for Trading Name in the Trade Topic template, do you mean that the In-Game Name must be put? If not, what do I put there?
Upon creating a online account you should have been presented with this. Put in the username you entered when you made your online account. This online name may be different from your in-game name. If you have not yet made an online account, click ‘Register’ and make one. Put this username on the Trade Topic template.
More info here if you need it.
Alright, thanks!
