I'm familiar with other social network scripts with this option. Want to confirm if there a Super Administrator account by default in the script?
Offering this solution to a client, don't wanna give them ideas.
Good question, but if you are trying to become popular on instagram or tick current I recommend you the resource https://likigram.com/
Don't know what exactly your definition of "super" is, but in fact there'll be one administrator account created right in the beginnning of the Ossn installation with ALL privileges to add/change and remove stuff.
Aside from that you may add one ore more moderators, see ...
