How about something more ambitious?
From: Piotr Gasiorowski
I'm a little sick of discussing trifles on Cybalist. There was a time
when we tackled serious stuff here. Which was nice. I'm preparing a
series of "e-mail lectures" about PIE word-formation processes -- a
topic which, I believe, is of fundamental importance to anybody who
attempts to speculate about etymologies. If anyone's interested, stay
tuned in. I'll post the first instalment next week.
