edit url of category and work with other domain

[Khriz]

using vbulletin anime forum for reference:

http://www.anime.com/forum (Forum)

One category is "descargas anime":
Its url is: http://www.anime.com/forum/forumdisp...escargas-anime

I would like to "edit that url" (if you edit it if possible)

then I would like to know q type edition would not go against the terms of vbulletin:

1 .-)
-Changing the url of the category ("vBulletin 4") and q work with a separate domain: an example: "www.descargasanime.com"
Y q function of the class forums on the basis of this domain.

* If you go against the rules to change the url to a domain then the other category:

2 .-)
-Change it for a subdomain: "www.subdominio.anime.com"
Y q function of the class forums on the basis of this subdomain.

* That would be like to shorten the url. If it still goes against the terms then:

3 .-)
-change the url to at least: www.anime.com/vbulletin4

which are possible and which are not against the terms and conditions?
