The *Bʰlog is “a website that hopes to provide an accessible but informed forum for all matters Indo-European”:
The idea for this website arose in the Fall of 2013, when two fables that I recorded for Archaeology Magazine went viral and were heard by hundreds of thousands of people who had never even heard of Proto-Indo-European or the Indo-European language family. The goal of the website is to keep that interest going. If you’re a layperson, feel free to send an e-mail to the *Bʰlog with questions you might have about Indo-European. If you’re a specialist and want to contribute to the site, just let me know and I will set you up an account.
It’s run by University of Kentucky linguist Andrew Byrd and vouched for by Piotr Gąsiorowski (from whose post I learned about it), so I have no hesitation in recommending it and will add it to my blogroll forthwith.
Update. It turns out that “Andrew Byrd … is the administrator of the *Bʰlog but almost all the stuff has been written by his students as a kind of out-of-class exercise, hence its uneven quality.” Caveat lector.
