I’ve noticed that the old edutalk.cc domain is broken on Radio Edutalk. I had a a couple of hundred or so links on this site to the .cc domain. Just used Better Search Replace – WordPress plugin to change edutalk.cc to edutalk.info which reported:

During the search/replace, 1 tables were searched, with 435 cells changed in 260 updates.

. Seems to have done the trick, I limited the search to the post content. Very much appreciate the plugin authors.
