The author of the best QuakeWorld location definitions - flintheart - has updated his pack today. From now on you can customize also quad, pent, ring and suit location names, same like you always could by changing e.g. loc_name_ra variable within the client.
/set loc_name_ra $2$0$0
/set loc_name_quad &c44fquad&cfff
The Location files are now part of the ezQuake package.
