It creates a entry in the list. How do you remove that entry at a later date?
Lets say I want to remove permissions for someone to use ShoutBox, then later give him access to it again.
I can do that all fine, but now my list is growing with these special permissions when in fact - nothing special about them anymore.
EDIT: I solved this on my own
To remove on, click on the column "NOT SET" and it will remove itself.
