How do you fit the game features in your roleplay?

As example, the FC chat iicly can be viewed as a private linkshell network provided to the FC members from the GC as a service, and the FC login message may be a prerecorded message played to a member every time s/he (re)connects its linkpearl to the FC linkshell network.

What about tools as duty finder, party finder, etc? Do you take them off or had found some reasonable reason (ah, the pun!) for being recognized? Has this already been discussed somewhere?
