I use fbsd most of the time, and have been trying to involve myself a bit with the project. Here's a bit of what I've done.

Ports

I have both ports I maintain and software that has been placed in the port database. I avoid putting my own software in the ports db as I'd prefer someone else to A) deign it worthy and B) make sure it works right. The only reason that the 'graphics/vp' is listed twice is that the original maintainer surrendered it back to ports@FreeBSD.org. If anyone wants it, I would be happy to relinquish maintainership of it.
