So a few days ago I posted about the knot URL changes for the wedding websites. I emailed the knot and at first, they asked if I signed up for a paid domain, which is something they now offer. The girl basically ignored my question and once I wrote back again, she said theknot will keep your old website URL and it will automatically connect to your new one (totally ignored my question on how long it will keep switching) and said if I wanted, I could buy a paid domain so I can have the URL match exactly. For now, I'll just leave it as is and if for some reason, it stops working, I'll pay, but I don't find it necessary. Hope this helps anyone who was a little confused!
