Many folks were having touble getting onto the site yesterday. Hopefully you got the letter you needed.
Yes... I thought it was just me having all the problems. Thanks so much. I did get the letter yesterday. :)
I think the A B and C were repeated because there weren't new ones added every day for people to vote on.
The time they are changed is variable. I have also missed letters because of this. I know it is hard to remember or not possible, but it is helpful to check back later in the day. They usually change sometime between 9 and 10 AM Eastern United States time. But sometimes it is considerably later.
