This Note is intended to correct a lack of attribution in the paper [Bro10]. That
paper cited the paper [Gil98], but without the paper in hand, I failed to state that
the definition of whiskered category is the same as the deônition of semi-regular
category in [Gil98]. Further, Proposition 5 of [Bro10] is the same as Proposition
1.2 of [Gil98].

'Resolutions of monoids' which is [Bro10, Section 6] is surely related to [Gil98,
Section 3] on 'Monoid presentations of groups', but the precise relationship needs
further work. Clearly we both started from ideas in the joint paper [BG89a].
