Permissions of a new share not right, how to correct?

[muppets4]

I've installed Sabnzbd and that is working like it should. I've created a new share, called downloads and put it on write through the webinterface. Now the downloads are complete and I want to put them in the right folders. But.....the permissions aren't right. I cannot move or delete the files.

It doesnt matter if I go in through the shares on the client computers of if I try straight from the HDA itself. 'Permission denied'

Lets solve this question by posting a link to somewhere else on this forum: http://forums.amahi.org/viewtopic.php?f=23&t=1740
