I am a linguist (originally from Switzerland, now based in England) and my main language is not Greek but Old (Church) Slavonic. I am currently working on passives & passive-like structures in early Slavonic texts which was the main reason for joining your forum. I am trying to compare the structure of the Slavonic text to the one of the Greek prototype (almost all of the ancient Sl. texts are translations from Greek).
I was following your discussions on the Greek middle/passive for quite a while and was deeply impressed by that.
