We were contacted by Seamus Smith who told us about some more sites for Technicians. I have just slightly tweaked the site to have two more pages in the menu structure: Technician Sites and Physics Teaching Sites.
One of the sites Seamus mentioned is TecHKnow which has a huge directory of sites, that makes our pages look a little weedy. But on the basis that anything that links back to them helps, I am leaving our pages up.
I am still searching for the motherload on Physics Teaching sites. If you know it, please let us know using our twitter handle @physicstp or the form below.
