[2021] How to introduce a Loan Cupboard?

Greetings @Lil Elfette that's a new one on me! Hopefully someone here can help you out with that!

Kind Regards

@Lil Elfette maybe if you could try and explain how you believe this Loan Cupboard works? I'll be honest, I'm intrigued myself now

It may be that other players use the system but do so under another name? It sounds quite unique.
