The circle levels are based on donations: Junior ($12); Silver ($120); Gold ($300); Diamond ($600); and Platinum ($1,200). As soon as you have donated the amount corresponding to a new circle level, your level of membership will be upgraded.
The Scarf Circle recognizes you for the time you invest in helping us to grow and activate our community of donors, giving you BP-Coins every time you take an action.
Once you have collected enough BP-Coins to increase your membership level, they will be automatically deducted from your account in exchange for a free level upgrade that recognizes the support you have given to World Scouting through The Scarf Circle. You will keep the remaining BP-Coins.
