Hey Sheila, I was having similar problems last night. I had to re-join the group. When you get to the board sign-in and then check if there is a link that says "join" under the main picture and above the general discussion board. If there is, you need to click that to join the group and you should be able to post things and whatnot just fine. If not, I don't know what the problem might be! I just know I was getting the same message last night and thats how I fixed it!
