If you're worldbuilding and/or language designing for your WIP and you'd like feedback, I've just started an ongoing workshop called "Wednesday Worldbuilding Workshop" over at my blog. I take 500 word submissions and discuss them in depth. Information about how to submit is here. Examples of the first two week's submissions can be found here, and here, for those who are curious.
Thanks to moderator ChaosTitan who gave me permission to post this, since it's particularly relevant to science fiction and fantasy folk!
Do pass this on to any of your friends who may be interested. I hope to see you over there.
