Features / Usability

hello all!

i'm trying to use tiki in a intranet environment, at the moment i'm feeding the tw with content but at this moment is unusable for the rest of people because i have no found t a feasible way for control access to content.
i.e if i mark a lot of pages as a restricted category i actually have to set permissions one to one page.

there is a way for set permissions to categories?

thanks for a great idea as is TikiWiki, is the best tool for manage knowledge and experience.
thanks to people that makes this posible!
