Did you notice that the NeuroTalk software now has a larger variety of smiles and graphocs available to put in posts?

You can see them on the right side of your text box (including a "more" button that you can click to see the full list of smiles/graphics).

Or you can see them in the smile pull down menu at the top of the text box (there is a "show all smiles" option at the bottom of that list that will show you the full list).
