I am computer literate but still spent MANY hours navigating your program to create an invitation for 15 guests. The program imported two email addresses that no longer exist and were not listed in my contacts. It did not allow me to change the email address of one and required I buy $10 in coins (50%of original purchase price) to send one more and wound up charging me double. This is outrageous. The program is not at all user-friendly and I will NEVER use it or recommend it to anyone. I had no idea of the charge, paid DOUBLE ($40) to send 15 invitations. It took hours and hours to navigate and Im totally frustrated.
