Anybody know how to get a PR into fluent-nhibernate?

[jeff-hagen]

I'd like to contrib, but there don't appear to be any maintainers left. Been trying to get a PR reviewed for a few months. There are a few missing features that I'd like to add, but if the project is dead, I don't want to waste my time. Anybody know what's going on? Can a new maintainer be nominated?
