Please remember that StokeIt is free for personal use. If you are a home user, you don't have to pay for it. Really, it's free, you can take it and not look back. That being said, if you really want to make a contribution, I wouldn't dream of arguing with you.
If you're a developer, why not take a shot at making a plugin. If you know some C, you should be able to jump right in. If you run into trouble, post a message in the forum and I'll be happy to help you out.
Speaking of the forum, we can always use some more friendly, helpful volunteers to forums and help answer questions or toss out improvement suggestions. Why not volunteer some of your time to answer questions and join in the discussions?
I can't say it enough, but your support is greatly apprecaiated. Thank you.
