No, not writing one. But its not like I sit down and instantly idea come pouring out of my brain, find their way to my keyboard and I just write out code. Designing such a race is more than just modding, its creative for the first parts. So you have to find a race, collect ideas, try different things to see whats possible or impossible to do in DF, then have a look at balancing and how they would fit with the other races, what the community wants... and then, just then you can start modding. And if I do another marathon session like this, I would do another fundraiser, which needs time to collect the cash.
People just donated to the human fundraiser, and Toady ones release with 15.000$ so if I would do one now, it would probably not be successful.
Kobolds just got a larger update, right before the humans did.
I have a smaller project I am working on now, which I have to thank Putnam for. Even if my take on it is very different.
