I'm also missing the E and F. And yes it is a pitty. But well that's live. I'm sure that there's a mistake somewhere in the system and someday it will be ok. I'm sure that this is not the intention to force people in joning or buying the missing letters. At least not on this site. There's too much friendship between the members and Miss Veronica for this type of behavior.
Don't jump the gun and delete the letters you have. I've been a member here for several years now and as far as I know this is a first and I'm sure it will be corrected at some point. In the mean time just go with the flow and enjoy this time of the year with your family. Have a blessed Christmas.
