That is a list of many WMS services, most of which will work with TF. Each one would need to be set up and configured separately, though.
I plan to make the configuration process a lot easier in the next version of TF. There are a few quirks to it right now, but is certainly possible to get servers up and running. Use the connection strings for the WMS servers that come pre-configured in TF to get started, or feel free to ask questions. What servers in particular are you looking to try out?
