Has just gone up on the Exosolar planets encyclopedia

It's still there (or was at least returned). http://www.exoplanet.eu/planet.php?p1=GJ+667C&p2=b

Haha. 
While this does seem to be the first confirmed planet orbiting the C-component of a multiple system, it certainly isn't the first planet found in a triple system. 16 Cygni, HD 40979, and HD 65216 are also triple (HD 41004 is if you count HD 41004 Bb as a brown dwarf).

The C component part is really an artifact of the designation systems. If we designate a triple system as (1-2)-3, where stars 1 and 2 form the close binary and 3 is the distant tertiary, the majority of planets in triple systems have been found around component 3, including GJ 667Cb. IIRC the only planet known around one of the stars in the close binary is HD 196885Ab, but this depends on whether the tertiary star BD+10 4351B is actually bound to the system.
