About This adds two BBCodes... [thread=xxxx] and [post=xxxx]. It allows you to link to a specific thread/post and the link will change if the URL structure ever changes. Installation Put the contents of the library directory into your XenForo library directory. Install the addon-dpThreadPostBbCode.xml file in your Admin Control Panel -> Install Add-on option. Usage It's pretty simple, [thread=1234]A thread[/thread] will create a link to thread ID 1234 with the anchor text "A thread".
