Usually, no one will contribute when something goes open source, unless the person already wanted to contribute.
Austin's right of course (is he ever wrong???) however, I think an additional aspect of this to consider is whether you are simply going open source, or if you're allowing contributor ...

I made an ugly patch for the latest (at the time of posting) SVN of UOFiddler. Someone with more experience could probably make it look a lot nicer, but this does the job.
