re: "Did you just reply to a two years old thread?"
Sheikh: Margaret's post was created today (11 Jan. 2011). But Margaret is a Forum user who first used the Forum a little over two years ago. So there are two dates that appear in the original post: the date for the post creation, and the date for the user's first Forum participation. You were looking at the wrong date.
It sounds like you have a pop-up/ad blocker in your browser. Could you please check if this is the case, and disable the blocker so that the pop-up chat window can load on your browser? Once you are connected to a chat agent, you should be able to initiate your verification.
I checked and it doesn't look like you are required to complete any verification process at the moment. The team will let you know if there is a need for any verification process in the future.
