hi, this is my first guide
1. Open heidisql and log in
2. Open "Characters"
3. When you opened "characters" then you will see "characters" again. press it.
4. Then click "Data"
5. Now you will see all the names of the characters on your private server
6. Now time to change the name. click on the name you want to change.
7. Now you can change ur name to almost everything..i'll change my character name from (Zatan) to (Arthas Menethil)
8. Now save, then start your server, when you done that just log in and have fun with your new name
Sorry for my english
