Are you talking about on blackberry messenger or here on the forum? If it is for BBM just hit the sym key twice and it will pull up symbols and smileys. If you are talking about within the forum just go to advanced when posting and use the drop down.
You can also use: : ) ; ) : P and other combo's to have smileys appear. Just leave out the space I included and you will see this . I hope this made since.
