I am also interested in volunteering in the Zürich / Aargau area. I am extremely flexible in terms of time at the moment, although hopefully I will find a job. I can speak a fair amount of German -- everyone tells me I underestimate my abilities (ZMP with very good) -- and can understand a moderate amount of Swiss German as well. My Swiss wife has absolutely no clue where I should look, so maybe someone here can help point me in the right direction.
