Don't use prillian or the chatbox. As for the sidebar box, what is the point to have 3 different who is online blocks??
If I have it up, it's only on the right side of the portal and not in the forum at all. Cause you have that info at the bottom any ways.
At least there are no bugs though. So you have the choice to install Prillian as well. If you don't use it don't install it. Some people will and makes a good feature for them.
I don't see it being removed from the package.
