You can open the Channel Settings window by right-clicking in a channel window, and selecting “Settings…” from the menu. In this window you can control all options available to each channel. However, most options require that you to have Operator status.

Depending on what your network allows, you may only see a “Ban List” tab, or you may see “Ban List”, “Exception List”, and “Invites List” tabs. In each tab you may add or remove entries. If adding an entry you may enter more than one in the entry field before clicking on “Add”. If you wish to modify an entry, double-click on it, it will then be inserted into the entry field, where you can modify it. To submit it to the server, press "Modify".
