To use those 3 scripts with RSI's website, you have to drag the 3 links below into your bookmarks toolbar.

• grab-org-nick-names Grabs all nick names of an organization to be used by follow-nick-names
  • You have to open the members tab of the organization
  • You do not have to be logged in for this script
  
  
• grab-all-friend-nick-names Grabs all nick names of your friend list to be used by follow-nick-names
  • You should open your account settings side panel first (might work without, but let's not stress it)
  • You do have to be logged in for this script!
  
  
• follow-nick-names Applies all nick names that you got from the other 2 scripts to your friend list
  • You do have to be logged in for this script!
  • You should open your account settings side panel first
  • Paste the result of either other script into the contact search box
