It's not that difficult, though it isn't as easy as it used to be. They've done some site adjustments since I joined and have made things more complicated, but you'll get the hang of it. I was completely lost when I first joined. You just have to stick it out and stay with it, and you'll start learning more and more as time goes on. Soon enough you'll be quite used to it, I assure you.
ohmaigawd, DOOD! I have a livejournal too and I don't understand it either. Like...how do those people add the graphic stuff or the stories? LiveJournal is quite complicated. <___< I will add you because...I only have a friend there; which sucks...quite hard. =)
