where his civilizations, including our own

Always! I just tend not post about it because I assume most people wouldn't be interested, and there's not always a lot to show that would be meaningful to someone who isn't super enthused about linguistics. _hannelore and I have been collaborating on a conworld + languages for the last few years, though (feel free to check out the wiki, which we just use so that we can easily access everything from everywhere and not lose track of unfinished projects).

And yourself?
