I am sorry but what do you mean? vBulletin is a very common forum application. This forum isnt much different than any of hte Invision Power Boards. If you explain what the issue is we can try to help.
The main thing is to get out what you want to say. If you have a problme with Soudn say it. You have to tell us exactly what the problem is for us to be able to help. We cant help you if we dont know what is wrong.
