Thanks for the link to the "Labarion" list. I just joined up and have posted a notification to the Theudiskon list to let them know about it as well. I'll also tell the Labarion folks about Theudiskon, as I imagine there will be some people there interested in Proto-Germanic.

I was just gramming Vort (who has also joined Labarion) to say how remarkably familiar the reconstructed Gallic looks to someone with a knowledge of early Germanic and a smattering of Latin. You can really see how easy it would have been for these "Celts" to communicate with their "Germanic" cousins.

Thanks again.
