I'm super excited!
The ineffable Mark of zompist.com is releasing the language construction kit in hold-in-you-hands-paper-form. Not only is it going to have everything the online version has, but it's going to have the 'less than easy to understand sections' more fleshed out. There's also more advanced conlanging stuff. I'm especially interested to see the word list section.
In regards to the language construction kit itself... When I first discovered that conlanging was actually a thing, and not just some personal idiosyncrasy, the language construction kit was one of the first things I found. It helped me immensely. I was able fill in the gaps of things I didn't know how to accomplish, and I got the feeling I was in not alone. There were others out there who had this same interest. There must be if one of them was taking the time to put out this much information on it, and of course there are.
March is the date, so any time now. I'll be watching for a link to Amazon and ordering as soon as I see it.
