So I see that they have Forged by <insert players name> <insert date, time, etc>

How do you insert all that to have a preview of the flame?

I'm not getting your question.
But I think that you wanna see a preview on the flame in-game.

There's a number of the flame.
For instance: Name of the flame. Forged by someone at a date. (####) <-- That's the number of the flame.
You open your toribash application > Main Menu > Options > Utils > Flame Browser and then copy the number of the flame to the space in front of 0. If you want to see more flames, put another flame number in front of 1, etc.

Yeah, that's right. Thanks.
