SAVE ME!polygon modeling problem!

[cganran]

i am a chinese who like maya very much.i am learning polygon modeling by myself  now.Recently ，i get some problems during study.How to use "insert edge loop tool" to make new edge loop.I mean ,i don't know how to choose old edge to make new edge loop i want!! I always make wrong direction of new edge loop.

insert edge loop tool will work whenever there is a topology that can support a loop. so to be on the safe side, always model in quads. good luck
