There was good advice at the end of the page. I think the first thing someone should do if they should win, is to keep their mouths shut until they talk to their financial advisor. Don't have one, hire one. Do not talk to family about it, and don't cash in that ticket until you're ducks are in a row. If you're smart, you can make your money grow.
I can just see what kind of hell family will put you through if they think you have money. Have it locked up for everyone's own good. If I should ever actually win, I've already envisioned the insanity that would follow.
Having said that, I'm going to try and remember to pick up a ticket this afternoon ;-)
