vbulletin 4 and old costumers
 

it seems vbulltin will be released soon , but my question is this one, old costumers will be able to upgrade for free, or we will have to pay if we upgrade to vb 4


or how it will work? , since it seems vb4 will be more expensive


and if we have blogs and projects, what will happen?

or we can upgrade to vb4 and then when we upgrade to vb5.. we will have to pay?
