Anyone else unable to reply to the "win gold bars" game email?

Jen_wb

Got an email asking me to join in on a game to win 20 gold bars, to enter you have to post a reply to the post and I did the game, and went to post my score but...I can't seem to find how to reply- or it wont let me (not sure which!)

Has anyone worked out how to do this or is it not possible for everyone to join in in which case, why did you guys bother to email me if I can't join in?!
