There are so many good add-ons here at xenforo.com in the "Resources" that it's really tough not to install a bunch. I was just wondering if your site gets slower based on the more add-ons that you install? What about security? Is your site more susceptible to attack/ hack with the more add-ons installed? Or does installing add-ons really have very little affect on your site? May even better it's performance?
