Building a map pack
 

Does anyone have an idea what to use to build a custom map pack? I'd like to put a bunch of favorite maps into one pk3 to offer to the players on our server, but am at a loss as to how to group them into one pk3. I'd appreciate it if someone can tell me what program to use to make the pk3. Thanks.

You could try using PakScape (search http://www.google.com or http://www.fileplanet.com for PakScape) and add them all to one .PK3. Just be careful you don't overwrite any files.
