I applied for a one-event membership and submitted payment, but my membership status says “pending”. Why?

A one-event (or multi-day, one event) is only valid for a specific day(s). Once we receive the payment for the membership and process it in the online system, your status will move to "pending" (from "unpaid"). On the day you chose for the membership to be valid, your status will move to "current". After that day(s), the status goes back to "lapsed". So, the "pending" status just tells you that we have processed your payment and that you will be a current member on the day(s) you chose to participate as a one-event.
