How to get smilies and BBCode to appear when composing a reply?

Hi,


Just a little query - in this support forum, when you're composing a reply, you can see the smilies    And bold text etc appear as you're typing.


But on my forum, when you're composing a reply clicking on bold brings up the BBCode tags [ b ] and the smilie tags too : ) rather than simply showing the smilies as you compose the reply, and also the bold, italic, underlined etc text.


How do you change it so you can see all that when composing a reply like on this support forum?

You have to turn on the wywsig editor it is a setting.

Thank you 


And how do you turn it on?
