Creating new threads help.
 

Well, on my site, when users create new threads, and they use the codes such as above, changing fonts and sizes, when clicked upon, it pops up as BB coding in the thread. Here on this site, when you click a new size, it automatically does it and shows the user. Do you know what I mean? I want it to be like that for users on my site so when they change a size, it does it instead of giving the BB code such as:

Code:
[SIZE= "4"] [/ SIZE]
