Removing NGUI Free Watermark

[reinancntw]

We're doing some school project and we are planning to use NGUI Free.
However, I think it would be an eyesore if the watermark is showing since we will present it to our professors.
Is there a way on how to prevent the watermarks from showing?
Note: We are not planning to release the game as it is for school purposes. And admittedly, I think the game will not be marketable.

I'll let you in on this awesome hack that gets rid of the watermark.

First start Unity.
Then go to Window -> Asset store
Then purchase NGUI.

Easy, if you want more life hacks let me know.

I don't even recommend using the free version of NGUI. It's so outdated now... But yes, if you want the watermark gone, you'd need the full version.
