Abstract
In this paper we show that forcings which are strongly proper for
stationarily many countable elementary submodels preserve each of the following
properties of topological spaces: countably tight; Lindel\"of; Rothberger;
Menger; and a strategic version of Rothberger. This extends results from Dow,
as well as from Iwasa and from Kada.
