After too many years of ignoring people asking me to sift my maps, I finally broke down and started. Here's the summary:
Unsifted: 2103 maps
SIFT 1: Map contains either "gamemode" "teamnumber" or "pball" - 656 maps
SIFT 2: Delete any maps with "beta" in the name - 645 maps
SIFT 3: Delete any maps with "jump" in the name - 615 maps (riverjumping.bsp was spared)
SIFT 4: Delete any maps with "alpha", "_b", or "test" in the name - 593 maps
SIFT 5: Delete any maps that I think are bad - 579 maps
Alright! The sifted maps and updated maps.torrent has been placed on my site! Enjoy!
