Did you ever hear back? I'm curious what kind of answer they would give. I'm thinking of sending an email asking about it, if they haven't responded elsewhere. If I click the link I get the message "Sorry 'techforums.nintendo.com' does not exist or is not available."
This is very interesting.
On the 23rd, I shot a PM to NoA Jane asking if she had found anything. She replied that she had and had actually replied to the thread on the previous day.
I quickly looked at her reply and planned to address it once I had time to deal with it (i.e., tonight).
When I went back today to check it, I'm pretty sure the reply has changed.
In both versions of the reply, there's the typical "your call is very important to us" language that tells me, pretty much, we are not getting our year back in our expiration dates.
However, in the version I swore I read the other day, Ms. Jane included a link for giving feedback regarding Club Nintendo. This paragraph/link is no longer there.
I would almost think I'm making this up... except that her reply in the thread is dated December 26th... and our PM exchange happened on the 23rd (where she said she replied the previous day).
So, basically, I'm pretty much going to say, we're SOL in having a reasonable way to determine our survey end dates on these older surveys.
