No need to approve
 

In one of my sub forums i have the "Moderate Threads " function enabled, but i want to set the permissions of one usergroup so they can post threads without my approval! How can i do this?

You will need to figure out the name of the setting (probably find it in the page source) and then set it to 'false' just for that usergroup in a plugin. But, as I said, first you need to look in the page source to get the name of the setting variable.

Try that and see if it works. I've never played around with that system, so I'm not sure if there is more involved than just that.
