well its pretty simple
all you gota do is go to joymax.com go in the aocunt someone is selling you, then go to games on joymax.com choose silkroad.then on the left of the page you see a bunch of tabs, choose support>bugreport. Then you accept bug report submission. Then on the page you are next taken to, click change character name, and click the server the character is in.You will then see all the characters that are in the account, Also copy and paste the name into rev6. Sometimes people can just change a small letter or a 'L' to 'i' etc. and look at the name very closely.
