I'd rather you use the user's "Friendly" name(ie: Player.getDisplayName()) than their account name.
On my server we use a lot of nicknames, to shorten things up, and to display people's actual names.
I would rather see their nicknames in the IRC than be forced to view their player name.
Please add this as an option, or switch to this.

Yeah will have this in next rb, been busy for the last 2 weeks and haven't had time to do much

Done in next version
