There are several places where fCraft shows players' names without formatting (rank prefix, rank colors, frozen/banned stars, or custom DisplayedName stuff). For example:
- logfile entries
- incoming and outgoing PMs
- /me
- rank chat
I would not consider real names in log files, but in other cases (pm, /me, rank chat) it's pretty much cosmetic. I suppose I could change it to show DisplayedName, but then it wouldn't stand out as much against other chat.
