I found Audacity when I started transferring my old vinyl LP:s to CD. After a while I also found this site, the Audacity Wiki.
I became really involved with this site when I started helping out cleaning up after spam attacks. Not being that well knowledgeable about the SW itself, I at least try to contribute by performing some minor "webmaster" chores, like e.g. cleaning up little editing mistakes and pruning redirect links.
