We're obviously using a lot of the same equipment, so maybe a for sale section would make sense.
Who wants an excellent condition 17-40mm F/4L? $550. Bitcoin accepted.
Because this community is spread all over the world (without antarctica, I believe) I suggest to specify shipping options.

PS: If someone located on an antarctic station is using ML and reading this I would be delighted. Consider delivering some input for escho's temperature survey. ;-)
