I have not promoted this here before, I think, but here it is. In 2009 I, with a couple of friends, started a forum for discussing theoretical and philosophical issues in archaeology. Anyway, The Philosophical Club for Archaeologists will convene again this month, so if you are interested come and join us. More info can be found on the Club website: http://faklubi.wordpress.com/in-english/ (also in Finnish). The upcoming event on Facebook.
