Hi all. FNG to this site. I've been shooting PPC indoor for some time now, but want to branch out to IPSC and IDPA. When I started reading the threads suggested for newcomers, I quickly found out that I don't understand some of the terminology used. Specifically "indexing". What the hell is it? I seem to think it's the motion of aquiring one target after the next, but...? Also, maybe they're could be a "glossery of terms" somewhere on this site for FNG's like me. Whatcha think?
