Make three new tabs,one for chat box,one where people can post news and updates(it shouldnt get mixed with questions tab),and another tab where people can post articles(not large ones,but small).The articles can be either moderated by the mods and admin in the forum or can be directly posted,that depends upon how you want it.
A different chatbox or a different tab can be made where users can only fight,it should be without boundaries.....(the last one is my personal point of view)
