The world of blogging

Okay, I know it seems like a rather simplistic thing to figure out, but for me it's like every other new thing on the computer. Computers have their own language, there own world, their own temperment, whatever --- I've had this blog for over a month now and I'm just figuring out how to actually post something to it. Aside from that, I don't know how to attach photos or links or anything else. I'm definately feeling like a duck out of water and am wondering why I've joined the world of blogging in the whole first place. Is this supposed to be fun?
