Fundraising tech/Essential systems

Systems we should be keeping an eye on all the time, and how they interact
Before any big campaign we should make sure all of these things are working. Also see Fundraising tech/Pre-campaign checklist.

Before any big change, we should understand how it will affect all of these things.

For a more general list of components see Fundraising tech/Components.
