Forum 2 Forums in 1
 

I have a forum in spanish, I'm using vBulletin 3.x with it. I want to make the same forum now but in english, with all categories and posts new and independent. The thing is that it's the same community so I don't want the users that are previously registered in the spanish one, need to register in the english one.

I would like to know if vBulleting in any of it's version can provide me with some feature that allows me to do what I need. If not, suggestions are welcome.

Thanks.
