I started with the knot right after we got engaged and have been thrilled with some things and not so happy with others. Uploading all our guest contact information was easy and all in one place. I really liked their free website and the fact that when someone RSVPd on our site, it updated their information in our contact list automatically and sent me an email saying who confirmed what. Their website was super easy to set up and all our guests have enjoyed looking at it. We have ordered a couple products from their site, one arrived no problem and the other had to be reshipped because their computer didn't take the full address I entered and I didn't catch it until the second time around, so a bit miffed there. I don't think I would order any more products from them, but the products we did order turned out perfectly and are of good quality. I think my favorite part of the whole site is their seating chart option! I just finished putting together a seating chart for 90 people in less than 2 hours, it was brilliant! Overall, I have really enjoyed working with this website for our wedding planning and have recommended it to some of my girlfriends who are soon getting married as well.
