Planning on invitations for your next party? Don't waste paper on invites that will only be thrown out. Here’s a bunch of virtual solutions:
 

1) Facebook:  easy peesy:   easy for your guests to rsvp, since facebook offers them the option right on the page (attending, maybe attending, not attending).  Easy for YOU to invite all your friends.  Or NOT.
 

Want something more formal? Here’s a few other electronic evites:
2)  Constant Contact: features similar to facebook like allowing guests to forward invites to their friends, and the ability to add pictures and a map. This site charges you for membership, but offers a free trial.
3)  pingg.com. Unlike facebook, Pingg has a variety of styles and artwork to personalize your e-invite. Fancy!
4)  Evite.com:  free, fun, easy- use their templates or create your own.
