BB Coding

Is there any way so that I can get on my forum any custom coding- Like I can make a random code or script, and whatever I want to result will result.

For example, this code will make the text blink: [blink] [/blink] even though the code doesn't exist- Sorry, if it's confusing.

Edited: I mean as if it it possible to make our own tags that will have a custom result, and will work on our forums, such as the blink example above.

so far i have never seen it on a forumotion board.unless i am missing it. but phpbb and many other forum have this option.
it's usually something that you have to install. to ware you can not install modules on forumotion forums yet. hopefully soon though.

Okay, thanks!
