OK. Thankyou.

I just was reading some old threads about the Mood feature. They're at the very bottom of the page that this thread is on.

One person had not read some comments people had posted on her photo album in her profile page. Once she read them she was able to access the mood feature.

Another person was using safari on a Mac and it didn't show the Moods dropdown menu. Once they changed to FF it worked fine.

all very weird.
