+- **ChangePolicyUpdateDefaultVotePolicy** - used to update the default vote policy from the policy of the DAO.
 - **AddMemberToRole** - used to add a member to a role in the DAO
 - **RemoveMemberFromRole** - used to remove a member from a role in the DAO
 - **FunctionCall** - used to a call a function on any valid account on the network including the DAO itself, any other DAO, or any other contract. This is a useful mechanism for extending the capabilities of the DAO without modifying or complicating the DAO contract code.  One can imagine a family of contracts built specifically to serve the DAO as agents, proxies, oracles and banks, for example.
