For those of you love simple machines forum (smf) or phpbb or [insert your favorite forum here] will probably like to know why I am installing Joomlaboard forum in this guide rather than something else. There are a few reasons
The ease of install wouldn’t stop me from showing you an SMF install or something else if it worked as close as Joomlaboard does with CB. Once JoomlaBoard is installed it works with the private messaging system you install for CB and it uses the profiles created in CB. There is also a plugin for CB to create a tab in the user’s profile page. The other forums lack this tight integration with Joomla/CB. So JoomlaBoard, for the moment at least, is the main choice for CB websites. The bad news is that there are some problems with Joomlaboard. From forums that I have read on various websites that use Joomlaboard (including Joomlapolis.com) I have seen recurring problems with this forum. An example would be Joomlaboards problem file attachments. Sometimes Joomlaboard just doesn’t allow an attachment to be up loaded. Joomlaboard is current working on a new version but I don’t know if it will fix the problems that people have been having with it. We can only hope at this point. All and all Joomlaboard will do what you want it to. You just may run in to an occasional mysterious hiccup that seems solvable. Just know that it may not be you or your users. It probably is just Joomlaboard misbehaving.
Now let's get to installing Joomlaboard.
From the Joomla administration control panel click on Installers>Components

Next, click the browse button

Navigate to the directory you downloaded Joomlaboard to, select the joomlaboard zip file and click the open button.

Click the Upload File & Install button

Wait while the file uploads to your server and you should be greeted with the following screen when it is done:

Click the the Continue... link at the bottom of the page and you are done. Well... You still have to configure your Joomlaboard. :)
