To Link or not to Link

I wish I knew more about computors. Grrrr! Today I'm trying to learn the art of linking and everything I read makes a lot of sence until I get down to the nitty gritty job of actually creating a link. I imagine that many of you have this same problem when it comes to computor mechanics--sheer panic! But I'm not giving up without a fight. A fight with brains over computor that is. And although I'm sure that one day I'll look back on this learning adventure with some sort of humor (if that's possible?) At least I can chalk it up to just one more thing that I've wrestled with and won!
