Fernando López-Menchero is still working on his self-learning course of Modern Indo-European. He did already publish a Modern Indo-European verb conjugator in ResearchGate:
I have been very busy with my PhD thesis for more than three years already (on Knee anatomy and pathology, nothing related to MIE), but while I wait to defend it I have written a small dissertation on the expansion of Indo-European-speaking peoples based on the latest genetic research:
You can find high-quality images at Indo-European migration maps (as always, they are licensed CC-BY-SA 3.0)
Apart from many details of the theory that will no doubt need to be corrected as more ancient DNA samples are published, I think the text (and images) help more clearly identify Indo-European-speaking communities, and more precisely which dialect of Proto-Indo-European we are trying to reconstruct and speak with this project.
As you know, Fernando’s Modern Indo-European Syntax already had some important corrections on the grammar, and we have to work with Antonio’s Spanish translation of the second edition of the grammar, which will require still more revisions before being published…
Together, all this work compels us to thoroughly revise some aspects of the grammar, and work harder to update the websites. We also want to improve interaction between us and with you. I hope to have some more free time within some months to make some important changes to the website.
Thank you all for your comments and mails, sorry if I wasn’t able to answer them all,
