Settings for WMS Plugin for JOSM

This plugin comes with a predefined set of WMS servers. I have been unable to get this plugin to display Yahoo Sat using JOSM on PCLinuxOS (KDE4.5). I get round this by using Ubuntu 10.04 and JOSM to display Yahoo Sat. Is anyone else using PCLinuxOS and JOSM and has managed to get the WMS plugin to display Yahoo Sat?

As a UK based mapper, the OS StreetView dataset has arrived as a backdrop in Potlach. Can this be accessed using WMS in JOSM? If so how is it done?

I think its easiest to use the SlippyMap plugin in JOSM to show the OS Streetview maps.

You’re right! I had not used the SlippyMap plugin before.
