A renewal is a member you already have, at a price you have already published, into a household that already exists. So there is nothing to approve.
No queue, no rows for a secretary to rubber-stamp, and usually nothing for the member to do either.
Most people do nothing at all
Last year's Direct Debit collects this year untouched. The member is not asked to set anything up, because they already did.
Where a Direct Debit has died, their renewal link offers them a fresh one there and then. Better than the club finding out when the collection fails.
The renewal link
Each member gets their own, in an email. It names one household and no more, so it is not a link to hand round. It is theirs.
If somebody has lost theirs, there is a box on the renewal page for their own email address. It sends the link to that address and nowhere else.
Why a wrong link and a real one look the same
Every refusal on that page reads identically. A made-up link, an old one, and a real one belonging to somebody who has left all get the same sentence.
That is on purpose. A page that answered differently for an address your club holds would be your membership list, readable one address at a time by anybody on the internet.
What they are renewed on
The category they were on last year, carried across by name.
It is not a picker. Offering the price list would let anybody renew as a Junior.
If you have retired the category somebody was on, the page says so plainly and sends them to the club. That is a conversation the software cannot have.
