Welcome, man!
As a great friend says, the easier way is to choose something you like, and start from there. It'll be a lot better to state your prefferences (Sci-fi, Warhammer, Ships, you name it), and you'll see a lot of people trying to help out.
Once you start building, please, post a thread with some pics, and share what you've learned. Anyway, there's a section of tools and tips, and you can dig many treasures of hobby knowledge in there.
So, make yourself comfortable, check the rules, ALWAYS listen to the Moderators (they're very accessible, gentle guys), and remember: ZEALOT is special because WE (INCLUDING YOU) make it so.
Welcome again,
Rogério
