So we've been supporting the "mood manager" plugin now for many years on the forums, although many, many people had problems getting it to work to change their mood. There haven't been any updates to this plugin for many, many years and we couldn't get it to work with many modern browsers.
Sadly, this is the end of the line for the mood manager.
You can continue to let others know what you're up to or how you're feeling, however, with the status updates that appear under your username in a post.
Sorry we had to let it go.
