Yeah, I believe it does....but is a long process to get put up I think.
The Cartographer's Choice Maps are those maps that the CLs feel are real standout maps from all the maps posted in the Finished maps forum. As I am sure you know, some of those are indeed awesome and choosing standouts might be a bit difficult . Once a map is suggested to the CLs as a candidate, they then get discussed on the CL threads, and if they agree, one of the CLs posts it up as a Choice Map.
However, this all comes down to the CLs having the time to do these things, and RL has a tendancy to put restraints on time available for our favorite mappy site. I am sure that they will be back, just give it some time
