Thanks George, this is a useful service. I would suggest that, whenever one of us goes to the trouble of looking up some habitat-related references or doing some calculations, that we enter it on the above wiki, so that everyone can find and benefit from it. I'll start doing this today (I'm currently looking into issues related to radiation shielding).

Best,
