I want to track how contributions were brought in. Is there a way to track that?

Use the referral source feature by putting “?source=X” into the URL. which appends X to the Source field on a Contribution page. Here’s an example of how that works. The link is: lp.org/join?source=AndyBurns

The Source field of the Contribution would then read: “Online Contribution: LP Membership – Andy Burns. Now you know Andy is helping to grow the LP 🙂
