All of the [forum] display mechanisms are templated. You can pass four templates -- template, header-template, link-template, and scrub-template.
They use the substitution style found in Interchange's attr-list ITL tag.
The following values are available for templating:
ADDITIONAL Additional text normally only used at the top level COMMENT Text of the message CREATED Created date in ISO format DATE Date the comment was made DISPLAY_URL URL to display the forum with a new starting point FORUM_APPEND End indent </UL> tags for item (automatic, don't use) FORUM_PREPEND Begin indent <UL> tags for item (automatic, don't use) MOD_TIME Modified date in ISO format PARENT_URL URL to call the parent of the comment REASON Text indicating reason for scoring REPLY_URL URL to reply to the commetn SCORE Score of the article SUBJECT Subject of the message SUBMIT_URL URL to submit a new top-level thread TOP_URL URL to call the top level of the thread (if not at top) USERINFO User information based on login status and anonymity
You can see how the above are used by examining the file pages/forum/display.html and playing around with the provided templates.
