When you first install the vBulletin forum, you can give the forum a name, but if you made a mistake, you can change it to something that is correct. Here's how:
1. Log into the administration page with your admin username and password.
2. Under Settings, click on Options.
3. Then from the All Settings list, choose Site Name / URL / Contact Details.
4. CLick on Edit Button at the bottom.
5. Now in the Forum Name, put in the new name you would like to use.
6. Now scroll all the way to the bottom and click on Save button.
