Hey Adam, We'd love some help. Can you join us on #librefm on irc.freenode.net or take a look at http://bugs.foocorp.net/projects/fm/issues
Generally we ask that people submit some patches before we give them commit access. Today you'd do that with a pull request. Feel free to ask questions on the list though, as the IRC channel is quieter lately with people working harder in their day jobs.
