This is a bingo addon for the guild Knights of Stranglethorn.
The only way to close the bingo frame is to click on the close button in the left corner of the frame.
To let the frame popup. Just type "/bingo" in the chat.
The text in the frames are NOT editable in World of Warcraft.
You can edit the frame texts in the .xml file.
It looks something like this: <FontString name="FontString2" inherits="GameFontHighlightSmall" text="Vardion is back before the break ends">
What red highlighted is. You can change that text.
