Did you go to the upper right hand corner of the forum page, where it says your screen name, when you last visited, and how many new private messages you have, if any? Underneath all of that should be a line that reads "My Mood" and then a mood should be displayed. Just click that and a drop down list of moods should display. Click on the mood of your choice and it should be the mood that displays in your posts, under your avatar and screen name and all of that.

Also, if may be helpful if we know what you OS is and what web browser you use, and if you have cleared your web cache recently.

In case you don't know what a cache is, it's just information from a website that your browser keeps in a file so it doesn't take a whole lot of time loading the site up when you revisit it. After a while, the browser can't save anymore information on the site and sometimes things on the site fail to load, especially if it's new information. Clearing out your cache every now and again refreshes your browser and allows new information on the site to be used and displayed.

You can clear out your cache under the options in your web browser. It's a bit different for each browser, so sharing with us what browser you use can help us to direct you to the right settings to be able to do this.
