Couldn't find any relevant previous questions on this subject - feel free to refer me if I missed something.
I have been impressed by Dropbox's feature voting system, Votebox - see https://www.dropbox.com/help/136 for a description.
I'd like to add something similar when I launch my product site - it looks like Dropbox have put a lot of work into their version - has anyone got positive experiences with any commercial (or OSS) products that achieve the same sort of thing?
I'd be happy with hosted or self-hosted, open source or commercial (as long as the licensing costs are reasonable). It just needs to integrate "seamlessly" into my site (e.g., features.mysite.com, etc.).
Many thanks in advance - Steve.
