I'd definitely contribute! I really like Haventon chronicles (more than Dragon Wars) and if I'm reading a serial, I'll always buy the ebook when it comes out (even if it's exactly the same as what was posted online).

Now for the perks, I'm one of those people that don't like physical books (I move too much, so it's more convenient to use ebooks), so I'd rather pay something like 25$ and have access to the raw manuscript as soon as editing is finalized.

Good luck! I really enjoy reading your work.
