There are four types of membership categories: Junior, Individual, Corporate and Scout Association. In each category, a provision has been made for members to grow in a seven-stage system starting from Copper to Bronze, Silver, Gold, Platinum, Emerald and Diamond.
Although Copper is the starting point for each of the categories, it does not mean that a member must start from Copper. One is free to enter from any of the stages.
However, the ranks allow for gradual contributions with the highest being the diamond membership. Members who wish to make contributions above and beyond the category payments are also welcome to do so.
