Forget it, I already see how to use it, but definetly is not intuitive have to select the Smiley. I thougt (and as I could see other users on your blog too) than just selecting the mood, this integrates a Smiley.
Hope as he says:
Hi, love this! Would love to have it so that when you select a mood it automatically assigns a mood icon. It’s kinda confusing that you have to select a mood and then a smiley, some members will not know that they have to select both. It should be a one click deal, select mood and then it shows the mood icon that is assigned to that mood, write your status and post it.
I know that it may be hard to have an icon for every mood but I think this approach is much more user friendly.
This could be a enhancement.
