This mod gives you the ability to create/edit/remove additional pages on your forum just like a CMS (content management system) would. After the installation of this mod you will see the "Page Management" section in the control panel. After you create a new page the link to it will be added to the forum's main menu. By editing the pages you can publish or hide any page, change permissions to make it viewable by any groups or limit who can view it based on the number of posts which you would specify. You can also, sort the pages in the menu in the desired order.
Since version 1.4 you can use special BBCodes to extend the mod's functionality:
[flashchat]http://path-to-your-flashchat/[/flashchat] - inserts FlashChat (if you have it) inside the page. This way members of your forum will stay in the forum environment after they go to the chat (by default they go to the new page outside the forum).
