  We review the status of the two-dimensional Abelian sandpile model as a
strong candidate to provide a lattice realization of logarithmic conformal
invariance with central charge c=-2. Evidence supporting this view is collected
from various aspects of the model. These include the study of some conformally
invariant boundary conditions, and the corresponding boundary condition
changing fields, the calculation of correlations of certain bulk and boundary
observables (the height variables) as well as a proper account of the necessary
dissipation, which allows for a physical understanding of some of the strange
but generic features of logarithmic theories.
