Hello*i need have some question about license.
 

I am thinking to buy this forum script*currently in 4.x version as i see in the website.My questions are that:"Can i use this license only for one domain name at a time? i can use it for all my domains?i must choose on which domain i want my license to be applied at my order?Do i have the license for a lifetime or i have to pay again after a year?When an update of the 4.x forum goes out i take it for free?ex.let's say i have the 4.0.0 version and a 4.0.1 version goes out*can i take this version for free?When new versions go out like 5.x can i upgrade to them and pay and have lifetime license?And do i have the option to stay on my current version and have my lifetime license*if i actually have a lifetime license.

Thank you :D
