Here's a breakdown of the steps, let me know if you need anymore clarification or are having issues!
1. Select Wedding Websites (from the navigation bar at the top)
2. Go to the RSVP section
3. Select the misspelled dish so it's highlighted
4. Under the box where you see the food choices there should be a text box. When you've highlighted the food the "Save" button, should turn into "Update" and "Cancel"
5. Edit the food choice in the white text box then select "Update"
A password just protects your site from anyone random viewing it, or writing into RSVP.
You'll obviously be reviewing the RSVPs anyways, but some people don't want their ceremony or accommodation details visible to anyone who stumbles upon your site.
