InsaneJournal

Okay, I could swear I've seen this asked here before, even with the same journal I'll be using as an example. I've gone back through 80 entries though, and I could swear it was more recently than that, so I'm sorry if this has already been answered! I don't know if I was imagining things or it was deleted or what but anyway.

Can someone tell me how to do something fancy in the namefield, such as this journal has? Where would I put it in the overrides, would it even be in the overrides at all, how would I code it, etc? Thank you!
