Weddings 2.0

No wedding planner? No problem: Planning weddings is much easier than it used to be because the Internet is here to help (although, no, you don't have to be like this couple and live-Tweet your wedding!). For save-the-dates, and maybe even invitations, check out our roundup of party e-vites. Bridal Guide has a save-the-date widget makes it easier for guests to add your wedding date to their calendars. OneWed's "Wedding Pre-Party" tool allows you to "Create your own private, invitation-only, personalized wedding planning site where the wedding party and wedding guests chat with the bride & groom and offer wedding planning tips, ideas, photos and more. Single guests can even scope out other singles before the big day!" Project Wedding lets you search vendor reviews by location. GroomsAdvice.com suggests creating a Twitter list of your possible vendors--you can ask them questions and chat easily.

MyRegistry.com allows couples to create a universal gift registry, adding items from any stores they want, as does Zankyou, which also lets you create a free wedding website. WeddingWire.com's Wedding Budget feature lets you easily set (and tweak) your budget and keep track of payments (they also have an iPhone app). Real Simple's Wedding Wine and Liquor calculator determines exactly how much booze you'll need to keep everyone in good, uh, spirits. fluidtables.com is a super-easy way to make wedding seating charts. As for where to seat cranky Aunt Selma...sorry, the internet hasn't found a solution for that one (yet).

Now you tell us: What's your favorite wedding site or app?
