Question before purchase
 

We are looking to purchase vBulletin to create our forum for information regarding Eminent Domain questions. I would like to know if it is possible to add advertisements at a later date for products we are offering or possibly from attorneys who pratice eminent domain law. If so is this feature available in vBulletin or would we need to purchase something else to add the advertisements or is there free software that would allow us to easily add the advertisements?
