We think all important occasions can use the uniqueness of a website to inform the group about the event.
Weddings are the most popular event to put on a website. Its true not everyone has a computer, but the majority do have some type of digital device:
cellphone, tablet, laptop... and its a great way to put out dates, directions, what to wear, and last minute changes so everyone can see them at once.
Just use an email address to get responses. How fancy is up to you. Here is a simple web site for a young couple
that just wanted their close friends and family to celebrate their wedding.
