I searched for this couln't find any thing about this so posted it here :)
The idea is that every X amount of custom maps is bundeled into a map pack which would be in a Subsection on the map page, Or could just be on the right side under a heading of Map Packs.
This way instead of manuely downloading+uploading custom maps we can get like 50 in at once much quicker and easier. Please think about this, if you can't do it thats ok.
