This simple little dialog will unban all , remove all from the except list and remove all from the invite list. It will also remove them one at a time as you need. Also once a ban , except or invite is removed the dialog will refresh the list accordingly. If you click another channel with the dialog open and click the " R " button it will then have the information for that channel in it. Also the list menu is the wy to go from the ban list , except list and invite list as needed.
