Help!

So I have been noticing on some of my friend's blogs (OK- mainly Jessica's) that there is this new fad going around- and it looks like something that I would really like to get in to- but I have no idea how to get going in it. Does anyone out there who reads my blog (which is pretty much nobody by the looks of my comments) have any hints or suggestions on digital scrapbooking. Ross has always wanted me to get into scrapbooking, because we have so many pictures that are displayed nicely in a box. A big box. I, however, have always kept far away from the whole scrapbooking frenzy because I have no original creative thoughts, and because I HATE the messes that come from paper and glue and all the other crap that goes into those super cute pages that I have no patience for (to make- not to look at). Anyway- after looking at all of Jessica's way cute pages on her digital scrapbooking album thing (which is super cute!) it occurred to me that she was able to do all of those pages without ever making a paper mess. It also seems that there would be something in the program like an undo button- I want that! Also- all my pictures would be on teh computer, so if I decide I want to change the size or the color options, or anything of that nature- I can! This pretty much sounds fantastic- except for one thing. I don't know where to go or how to get started. Is there a site you do it on, or do I have to download a program, or am I too dumb to attempt something like this?
