Should I include a link to our wedsite?

In the technological and ecological age, mentioning the wedding website on your invitation is completely acceptable. Place the web address, or URL, in the lower left corner of the invitation, in the spot traditionally used for noting R.S.V.P. information. If your invitation is getting crowded, a business-card-size enclosure can convey this data (it can function as an at-home card as well, giving people your post-wedding contact info for their address book)
