Topological Modular Forms of Level 3

We describe and compute the homotopy of spectra of topological modular forms of level 3. We give some computations related to the "building complex" associated to level 3 structures at the prime 2. Finally, we note the existence of a number of connective models of the spectrum TMF(Gamma_0(3)).
Comment: This was submitted to the journal in 2006. Apparently I neglected to upload it to arXiv between then and now
