@dspeakes: The New Updates I believe displays the last six occasions when someone has responded to either a post you've made or a thread on which you've posted. "Word Association" is an example of the latter. It also it shows when someone "likes" one of your posts.
The irritating thing with WA is that it doesn't let go and continues to report who just posted on the thread, even though I haven't been on the thread for weeks and weeks and have made many other posts since then. In the whole scope of things though, this is not really all
that important.

I intend to live forever. So far, so good.
