As has been already been post in some post's describing permissions and forum rules. When we go to forums and respond or view comments the user who post have badges and other other badges like Wizop, Administrator or other showing site status. Also below user name are badges, Perhaps some descriptions stating what all the badges icon means in descriptive words. I believe some users will find this useful in trust of the words spoken and quality of the the product they offer.
Ok i have spoke my 2 cents.
