Arhangel'skii proved that if a first countable Hausdorff space is Lindel\"of,
then its cardinality is at most $2^{\aleph_0}$. Such a clean upper bound for
Lindel\"of spaces in the larger class of spaces whose points are ${\sf
G}_{\delta}$ has been more elusive. In this paper we continue the agenda
started in F.D. Tall, On the cardinality of Lindel\"of spaces with points
$G_{\delta}$, Topology and its Applications 63 (1995), 21 - 38, of considering
the cardinality problem for spaces satisfying stronger versions of the
Lindel\"of property.
