Hi :o)
For me, agnosticism is being unable to answer 'yes' or 'no' to the question 'Do you believe in God'. There is insufficient evidence on either side, so I sit on the fence. It's surprisingly comfortable ;o)
ETA: In my personal version of agnosticism, being agnostic re God's existence doesn't mean being agnostic about the existence of an afterlife or spiritual plane, both of which I firmly believe in.
