Welcome!

There are lots of things to work on. I recommend pulling the code and perusing it to learn, and there are lots of "todo" marked around and so on which could pull you in for a first contribution. (First contribution is usually via patch, then we get you set up with commit permissions after that.) Perusing the forums can find discussions of things we should do but haven't yet. If you a more deliberate/structured task such as adding a new command or functionality, you could look at our task bucket via the Development -> Project Management link; that part is housed in codeplex.

Let us know if you have any questions/comments. While Fastalanasa and I haven't been contributing much code lately due to lack of time, we're still watching and able to respond to the forum daily. (Actually I may have a day or two coming up to code during this holiday break.)
