[R] CRAN mirror - howto?

[M.Kondrin]

Hello!
There is a group of administartors of Russian internet site 
www.linuxportal.ru (this is mainly a forum for linux-users) who are 
intended to host on this site mirrors of linux distributions and open 
source software with http and ftp access. I have proposed to them to 
open there a CRAN mirror, making a point what this site would be a first 
R mirror in .ru domain, and they seems to accept the idea.
Wouldn't you explain what is the procedure of opening of "official" CRAN 
mirror (i.e. site listed among CRAN mirrors on cran.r-project.org page) 
or whom I should contact with. I can not find this information on main R 
site.
