I don't really understand how this would work, there is a paid request section for Paid Modifications and a free modifications section. Trying to bridge these two areas would probably create problems.

If you chip-in then the coder is basically under an obligation to do what you ask, essentially you are asking for a Paid modification (or addition to a modification). What would happen if the coder decided to take your chip-in and not add the feature you wanted?

I doubt vB.org would be willing to adopt your feature as it would increase their responsibilities in managing modifications and users, something which they would probably want to avoid.

I think the current scheme of things work just fine, if you want to donate to someone then you can if however you want a paid modification you can post in the paid requests section.
