A common thing for new community owners is to get trigger happy with addons, especially those of the cheap/free nature. Ask yourself some of these questions before installing an add on... Does this addition make my community better, Is this value added? Is this something my users will notice? Will it even show on mobile platforms? Am i willing to not upgrade my site while i wait on the add-on to be updated? Does the majority of my community even care if i add this? If you answered no to any of these ,,, then i would suggest you do not install. Addons can be huge security risks, can make upgrading very difficult and can cause multiple issues with the site. That's just the obvious... heavier addons like gallery, blogs and CMS can hurt a community because it takes content and hides it on the site, less than 25% of the users on a community even visit these features , they can be heavy, bulky and slow and generally do not take mobile users into account which is a common mistake and when you have site features that have tumbleweeds rolling through it looks bad on the entire community. As for the seasoned forum owner i challenge you to audit your own community , does your community really need all them addons?
