I'd like to think that this guild isn't dead. It appears that if it was, it's very easy to revive. As for me, I've been on and off gaia for a while (real life chaos). I haven't really been actively developing my languages. I've got so many, I get distracted easily. I was working on a project that didn't involve math, but I haven't done that one for over a year.
The most I've worked on my projects within the last year is trying to develop a writing system for Rukogian (that name doesn't actually fit with the phonetics of Rukogian).
I'm thinking of applying ASL grammar to Emremasunian and a verb system similar to Japanese might be useful to add to . . . a language I haven't a clue what to call.
