CMS Made Simple Forums

Hi,
With the standard install of CMSMS all backend users can use their associated group privileges on all content pages. I wondered if anyone knows of a module or another way that backend users can be assigned access permissions for specific content pages and sub-pages?
Many thanks in advance.
Mat.

Ok, I have pretty much got things working as required using the owner and additional editor permissions + the save bug fix detailed here:http://forum.cmsmadesimple.org/index.php/topic,16495.0.html
