The YeastPheromoneModel.org wiki was created mainly by Ty Thomson from MIT. Kirsten Benjamin from the Molecular Sciences Institute was also heavily involved with some of the assumptions made, and other decisions involving the wiki. Jim Faeder from Los Alamos National Lab was extraordinarily helpful in implementing new Imported:YPM/BioNetGen features in response to our needs.

This wiki is currently hosted off a computer in the Endy Lab at MIT. Its content is being maintained by Ty Thomson (with hopes that other interested parties in the field will become major contributors), and the technical side of the site is being maintained by Ilya Sytchev.
