<h3>Creating a forum</h3>
|
|
<p>The forum module uses taxonomy to organize itself. To create a forum you first have to create a <a href=\"%taxonomy\">taxonomy vocabulary</a>. When doing this, choose a sensible name for it (such as \"fora\") and make sure under \"Types\" that \"forum\" is selected. Once you have done this, <a href=\"%taxo-terms\">add some terms</a> to it. Each term will become a forum. If you fill in the description field, users will be given additonal information about the forum on the main forum page. For example: \"troubleshooting\" - \"Please ask your questions here.\"</p>
|
|
<p>When you are happy with your vocabulary, go to <a href=\"%forums\">administer » settings » forum</a> and set <strong>Forum vocabulary</strong> to the one you have just created. There will now be fora active on the site. For users to access them they must have the \"access content\" <a href=\"%permission\">permission</a> and to create a topic they must have the \"create forum topics\" <a href=\"%permission\">permission</a>. These permissions can be set in the <a href=\"%permission\">permission</a> pages.</p>
|
|
<h4>Icons</h4>
|
|
<p>To disable icons, set the icon path as blank in <a href=\"%forums\">administer » settings » forum</a>.</p>
|
|
<p>All files in the icon directory are assumed to be images. You may use images of whatever size you wish, but it is recommended to use 15x15 or 16x16.</p>", array("%taxonomy" => url('admin/taxonomy/add/vocabulary'), '%taxo-terms' => url('admin/taxonomy'), '%forums' => url('admin/settings/forum'), '%permission' => url('admin/user/configure/permission')));
