There are several creators who I would love to be able to pledge at one of their higher tiers but they are limited and at capacity. It would be great if there was a way for me to subscribe to (email?) notifications for when a slot becomes available, to give me the best chance of nabbing it before some lucky devil who happens to browse to the creator’s page at that time does. I feel that this would reward loyal patrons.
Alternatively, a queue system would be even better, but I imagine much more challenging to implement, since I guess it would require holding a payment in some sort of pre-authorised state.
