Emergent baptism?

Here's a thought - where does the practice of baptism fit into the emergent church? Is it something that's happening in the alternative gatherings of folk to serve and worship, or has it been thrown out as irrelevant, along with all the traditional "church" stuff?

It just struck me that I haven't heard anything about baptism at all - nothing mentioned anywhere.

And yet it's a strong and Biblical part of committment to Jesus, a visual and public step in walking in God's way. So where is it?

If anyone reading this knows, I'd really like to hear it!

::further thought::
Do only pastors get to baptise? Is this why baptism isn't around in emergent groups led by the man-in-the-street, or by former pastors who have left the institutional church for a different way? Or is baptism just not relevant in the emerging movement?

::and one more thought::
Baptism is first mentioned in Matthew when John is out in the desert baptising folk. So where did it start? Who started it? Why?
