Idrettsforeningen Ørn is a sports club based in Skien. The club has an official website and is currently working on setting up a new website to improve communication with members and interested parties.
One of the unique opportunities the club offers is the opportunity for individuals to become a Grassroots Donor. Through the Grasrotandelen, players at Norsk Tipping can support the club at no cost to themselves. Up to 7 percent of the betting stake goes to the chosen grassroots recipient, which provides the club with an important source of income.
