Hello, me again, finally!
It's been a VERY long time, but I've finally got back on. Now, I'm sure something like this will have been attempted before, but I've had an idea:
Use Google Drive to create a collaborative compilation of all knowledge of (and ideas for) Tau language in Advanced Tau Tactica!
If you are interested and want to work on it, or just see it progress, please private message me you Gmail address, and I shall share the document with you.
If you are interested, and have no knowledge of Gmail or Google Drive (the latter being more likely), please comment, and I (or some other helpful person) shall explain.
