<h4>Containers</h4>
|
|
By designating a forum as a Container, users are not allowed to post into that forum. The forum will be visible on the forum listing page, so it acts as a section delimiter if you will. This is useful if you have a lots of forums which are nested. For example,
|
|
<br /><br />
|
|
Marketing<br />
|
|
-- Market research<br />
|
|
-- Brand management<br />
|
|
<br />
|
|
Sales<br />
|
|
-- Closing the deal<br />
|
|
-- Avoiding ear and throat pain<br />
|
|
<br />
|
|
If you don't want people posting into the Marketing or Sales folders, you designate them as Containers.<br />
|
|
<br />
|
|
<h4>Icons</h4>
|
|
To disable icons, set the icon paths as blank in Admin -> Site Configuration -> Forum<br />
|
|
<br />
|
|
All files in the icon directory are assumed to be images. Usually it is best to use GIF or JPG files as icons.
|
|
You may use images of whatever size you wish, but it is customary to use 15x15 or 16x16.
