[offtopic]This is a MyCode for saying something not related to the topic[/offtopic]

[Joshee]

This is just something simple for when you want to say something off topic. It's not really that great, but it's just something fun I thought of.

Expression:

\[offtopic\](.*?)\[/offtopic\]

Replacement:

<span style="opacity: 0.5;filter: alpha(opacity=50);">$1</span>

That's it! It basically just changes the opacity of the off topic content to 50%.

Let me know if there's any problems!
