Let your visitors leave their best wishes for you and your fiancée. Entries can be added in real-time with some services so that you can see who has visited your site and left comments.
Setup a page on your wedding website to outline all the events and gatherings prior to your wedding. You can provide directions to your events and you could even upload maps or provide links to an online map service to assure no one gets lost.
Who is in your Wedding party?
Everyone always wants to know who you have selected to be in your wedding party. Create a special page just for them; include bios' photos' stories and more.
Link to Gift Registries
Letting people know where you are registered can sometimes be awkward since wedding etiquette claims listing your gift registry on a wedding invitation is a no-no. Adding this information to your site makes for a great way to let everyone know where you are registered.
Offer Online RSVP
Save time, money and stress by allowing guests to RSVP right on your own site. Most services offer this feature and will send you an e-mail immediately when someone RSVP's. You can also login to your site to the saved RSVP's to keep track of who has and hasn't responded.
