Abstract
We examine several resummation methods for computing higher order corrections to the finite temperature effective potential, in the context of a scalar theory. We show by explicit calculation to four loops that dressing the propagator, not the vertex, of the one-loop tadpole correctly counts ``daisy'' and ``super-daisy'' diagrams.
