I saw a similar add on that pops up a message box with a few functions, but me personally, as a RPer i wanted something simple and instant.

So I came up with this mod.

It has one function and no settings. No options. All it has is a slash command /ooc

How does it work? Simple.

Install the addon, load WoW up, and then type this in your chat box:

/ooc Just testing a mod out.

What gets printed is:

(( Just testing a mod out. ))

That's it.
Converts anything you type after the /ooc into double bracketted RP OOC text. For those that don't Role Play, don't worry, click your back button now. ;-)

It will only do this in the /say channel. Since that's where you do most of your RP, that's all that I feel is really needed.

Enjoy.
