First of all and since Mark felt he didn't want to "polute" his but keep it intact for historical reasons, start with a new public repository (or a clone of Mark's) in SF or github or wherever.
Once that is done I would make a post in "Third party" asking for contributions but only if you can make a commitment to engage as maintainer of the port for at least some years.
Even then, don't expect to be swamped by request to be volunteer: very few people use FV nowadays and those few that do are, for the most part, maintainers of (very) old projects w/out a real need for this tool.
