MOST has detected the differential rotation of spots on a number of stars. We have developed the program StarSpotz to define the spots and derive the range in best-fit values of the relevant stellar parameters. Markov Chain Monte Carlo (MCMC) and Parallel Tempering techniques have been applied to eliminate the correlation among parameters and the non-uniqueness issues often associated with photometric spot-modeling. We illustrate the effectiveness of these techniques by applying them to MOST's recent observations of the spotted star epsilon Eridani. When combined with the accurate, near-continuous photometry returned by MOST, these techniques should be able to constrain theories of the exact nature of the differential rotation profiles of stars.
