NO you dont need to become a member - just click link, and there you see a little box next to 'download' where you enter the three characters shown to its left. after you enter click download and if ou are not a member you wait for lik 45 seconds and it'll ask you where to save.
if i may suggest in general, IZarc (
http://www.izarc.org/ ) is an excellent extractor that deals with a ton of file formats: 7-ZIP, A, ACE, ARC, ARJ, B64, BH, BIN, BZ2, BZA, C2D, CAB, CDI, CPIO, DEB, ENC, GCA, GZ, GZA, HA, IMG, ISO, JAR, LHA, LIB, LZH, MDF, MBF, MIM, NRG, PAK, PDI, PK3, RAR, RPM, TAR, TAZ, TBZ, TGZ, TZ, UUE, WAR, XXE, YZ1, Z, ZIP, ZOO. its interface is like winzip so its not new. its free so its worth having a look at.
