A Few Important Questions!
 

Well I am thinking about buying a vBulletin 4 and I need to confirm somethings before I buy it!

So here goes;
1. If I buy the vBulletin 4 FORUM LICENSE(not suite or whatever it is) will I be able to choose vBulletin 3 instead of vBulletin 4? If I cannot do this can you tell me how to get a vBulletin 3 LICENSE that has not been used please?
2. I currently have an SMF Forum and I want to be able to switch everything I currently have there to the vBulletin, will I be able to transfer my SMF stuff to the vBulletin for free and how?
3. After I import my stuff from SMF(if possible) I want to change the domain but I don't want to just "throw-out" my old domain so I am asking if I am able to have two domains for one vBulletin license/one forum. What I want to do is say my old member don't remember the new domain so if they type in, for example: www.domain#1.com I want it to direct them to the forum but show the new domain in the top (www.domain#2.com). I know how to do this it is just a matter that I am asking if I am ALOUD to do this and if I will get in trouble or not if I do this!
4. I believe that I had more questions but I cannot think of them so I will edit this with the other questions if I can think of them -_-.

Please answer these soon as I will most likely be getting my vBulletin by this weekend hopefully!
