Before you can create any prefixes, you must create one or more prefix sets. Prefix sets are simply a way of tying together related prefixes. When you select which channels will allow prefixes, you will enable one or more prefix sets for the channel.
The following options are on the page for adding/editing a prefix set:
- Prefix Set ID - This is the unique identifier for this prefix set. Only one set can have this value and the value may only contain A-Z, a-z, 0-9, and _ (underscores) only. Once you pick a prefix set id, you will not have a chance to change it (it will not be editable when editing the prefix set).
- Title - This is the title of this prefix set. You should not use any special HTML markup. It will be shown when administering content prefixes or if a user must choose between prefixes in more than one set.
- Use Prefix Set in These Forums - Prefix sets must be attached to forums before they can be used. Select the forum or forums this prefix set will be available in using this field. Once you do this, when a user creates a new topic in a selected forum, he or she will be able to select a prefix from this set.
- Display Order - The sorting order for sets. Sets with lower values will be shown before sets with higher values. Note that the display order setting for individual prefixes only controls their order within the set.
