There are two types of Pledges:
•Continuous – a continuous pledge must be created when a supporter promises to donate a certain amount of money at a set frequency, indefinitely. For example, a supporter may promise to donate $100 a month. This is the most common type of pledge.
•Fixed – a fixed pledge must be created when a supporter promises to donate a certain amount of money over a specified period of time. For example, a supporter may promise to donate $600 over a period of 6 months in instalments of $100.
