  We give examples of spaces which are good and bad at different primes in the
sense of Bousfield and Kan in any arbitrary combination and investigate which
impact the existence of a Sylow $p$-subgroup has on the homotopy type on the
classifying space and under which conditions the homotopy type of wedges of
classifying spaces is good or bad for a solid ring $R$. We give results
relating to various other $R$-homological structures and a collection of
examples.
