I ran across this site - http://www.olimpia.com:8084/magazine-index.html that was developed for the NMRA, but they never picked it up. Since it is located in a guy's basement in Virginia, no telling how up to date it is or how long it will be up and running. The search engine will bring up different results for Frisco (135 hits) and SLSF (203 hits), depending on the tags that were applied.
