My usual answer regarding additional writers at this time is "no". The bar for entry into the core team has been set obscenely high. As such, any additional writers will likely be third-party, when the system is in place for anyone to write up their own thing and distribute it.
I've made the hunger system not change your size as long as you're within 30-70 fullness. It's also a lot easier to hunt and actually find something, and hunger decreases slower than it used to.
Any additional changes to the system will probably have to wait a significant amount of time, as I'm currently messing with the combat system slightly, and then finishing up the major project I started last month, and maybe getting things set up for third party writers because I'm getting asked about female content repeatedly. Soooo its a minimum of 3 months away and probably more than that.
