When you are communicating on AIM, smileys can be quite expressive. You could want to communicate that you are Smiling, Frowning, Serious, Winking, Surprised, Kissing, Yelling, Ecstatic, or any of other shade of emotion.
But, the run of the mill smileys just do not cut it any more. And it will seem too much to go ahead and "buy" smileys. Well, the solution is free AIM smileys.
That is a site run by a friend of mine on the DP forums. Knowing him, I can assure you that he will keep adding value to the site. So, what are you waiting for. Go ahead and get your AIM smileys now.
