This add-on allows you to specify the forums that will "pin" the first post of the topic to the pages of this topic.
You can specify this on each forum, and the first message will appear on all pages, just like on the first page.
To attach any post, edit the thread or edit the post using the "advanced options" and set the appropriate counter or checkbox.
On forums that force sticky first post, sticky any post requires the message "Can override always sticky post".
