We define a moduli space of marked hyperbolic structures on an infinite type surface, analogous to Teichmueller spaces. The mapping class group of the surface acts on this marked moduli space. For infinite type surfaces, the mapping class group is a topological group, so we can ask if the above action is continuous. We answer this in the affirmative.
