The ExtraMissions.zip (14.9 MB) for Blizzard's Stracraft/Broodwar is now at
http://users.telenet.be/lena151  
Just go there, right-click the zip-file and choose "save as ..." to start 
download. This file contains 94 of the best singleplayer levels ever made 
and is freely available for all of you who still have their Starcraft/Broodwar
CD's lying around. BTW there is a readme file included to get you started.
I've had some complaints that this zipfile with the ExtraMissions for Starcraft/
Broodwar were lost because of the worm attack on www.starcraft.org
(see also my post 12/18 in alt.games)
