Opportunities in Samaritan parlance are akin to "activities." If we want to paint a park bench, we like to think of it as an "opportunity" to paint a park bench. If we write a grant, we like to think of it as an "opportunity" to write a grant.
There are good reasons to give some thought to the way you present your opportunities. If your opportunity is well-presented, it will attract more attention from potential volunteers. It is in the "Opportunities" work area where we can setup our accounts to track information that will become important when it comes time to work with our objectives and impact tracking.
