How do I change a word in post automatically?

[Abhik]

Hello..
How can I change specific words in posts automatically? Kind of filtering the words.

Like, if someone posts "vBulletin", it'll become "vB^ll3tin".

I searched a lot for mods and all, But, didn't find anything for vB 3.8.4 :(

I believe the censor options will do this

You could use Replacement Variables, but they will replace the words everywhere on your site. I have also posted a plugin several times that uses str_replace to do it for only the post message. You can try a search for it.
