forum permissions

[edspace]

Hello.
In my efforts of trying to translate vbulletin into another language i am having a hard time translating the forum permission table that is displayed at the bottom of the forums.

ex:

You may not post new threads
You may not post replies
You may not post attachments
You may not edit your posts

I want to change the word "not" into something else but i don't know which file is responsible for this word. The template forumrules calls $forum[postnew], $forum[postreply] .....etc.

Can someone tell me which php file builds the $forum variable and how i can change the word "not".

I appreciate your help.
