From a new-user perspective, I can see how the Forum Funding System could be considered a bit adhoc and hazy. When first researching on how to write a FFS-specific proposal, it was only by chance that I stumbled upon the FFS sticky and even then, the wording seemed more like a proposal than a codified standard.
I propose that a clear document (or site-specific area of intention), with clear methods or visual cues (and/or a possible diagram), be implemented. The goal of such an implementation would be to produce an end result that would invite more users to learn about (and use) the Forum Funding System.
In terms of producing a graphic/diagram, I would vouch for something similar to Monero's governance process as it is colourful and logically clear.
More importantly, I would also propose a revamp of the current 'multiple-category' system or move to a site-specific area or even move away from the forum altogether but keep the crowdfunding aspect intact; possibly moving to a different system altogether. To do something like that would require more effort but I think would be beneficial to overall economics and trading.
I'm curious to hear input from the more experienced forum users here. I hope that we can produce something more flexible, informative, and inviting.
