I don't think this needs a special area. Here or on the composition forum would both be great places for such a discussion. The AKWN site you list is always my first visit when worrying about modern vocabulary. It might be nice to subject his list to unicodification at some point.

I was looking for something completely different but sometimes you do have to love search engines' irrelevant results. Thisone is in modern Greek but the articles in the middle are in ancient Greek.
