i suggest make secondary usergroups depend on the language they prefer or native language
this will enable control different users that they use thier language to post
so we can make someforums not for specific language users
also to send e-mail or offers depend on the language when they belong to secondary group
seconday user group :
english users
arabic users
and so on
this is should depend on what they choose from the registeration as thier native language
and with ability to change it if he choose incorrect language for him
and then he will transfered to another secondary usergroup
i use vbet for one year before i stop it temporarly untill i finish upgrade to vb 4 with fixed all bugs
and there are already users from different countries and i want some specific control also depend on thier mother language
