The Warcraft WordPress theme comes with bbPress forum support and custom design integration.
To install it you need 2 main steps:
bbPress significantly simplified forum installation and configuration. Simply install from plugins section, activate and add Forums link to your menu and you’re done.
Install forum from: Plugins > Add New > bbPress forum
click activate and you’re done.
Now you are ready to create forums and Topics within the forums.
TIP: WordPress and bbPress users do not need separate registration to your blog or forum. one registration is enough for both, but WordPress and bbPress have separate permissions settings to the same user.
For example, same user can be restricted from posting anything in WordPress blog but be allowed to post in bbPress forums in any capacity.
