On our wish list: LinkedIn integration is nice; but some of us are Facebook people too.
MyPunchbowl
What it does: Helps you plan parties, organize what people bring, and send vital information to guests (directions, invitations and save the dates). It's like evite, but better, and more elegantly designed.
How to use it: Go to MyPunchbowl.com and click on the "create a free account button." After registering, party planning is a step-by-step process that anyone can follow. You'll be taken to a simple landing page that allows you to enter the name of your event and you can get started.
Merry Web 2.0: We loved the user interface for its simple tabular environment (that tabs include a "dashboard" and an "address book," which is helpful for guest management). The light blue and white is colors were easy on the eyes, and avoided the pitfalls of other loudly designed party planning sites. The "poll for a date" function is pretty helpful tool for those of you who agonize over the best time that will guarantee your favorite guests to be in attendance. The ability to release a pot luck list is great for both you and guests; they can say what they're bringing, you can keep it in an organized area without having to deal with a bunch of reply "I'll bring this" e-mails like you normally would.
On our wish list: MyPunchbowl works great on Mozilla Firefox and Microsoft Internet Explorer, but there have been some "layout issues" with Safari for all you Apple lovers out there. In its FAQ section, however, MyPunchbowl says they're addressing the problem and they expect the kinks to be worked out of the next major Safari release. Also, you'll find pretty limited mobile access on your browser, but there is MyPunchbowl Buzz, an RSS tool, that the company says works on mobile phones. It updates a user of changes (say, someone added a potluck dish).
