This is the thread's initial revision.
Hello again :-) In case you haven't picked it up from other places, the old language bar template is no longer to be used in new pages. Where it exists in old pages we are leaving it until we know for sure that all the translations already done are migrated to the new translation system. We have more guidance pages now than we had when we did the klassroom - you may be interested in them, so start at Tasks_and_Tools.
Your work on the plasmoid was perfectly timed to match in with Aseigo's plasmoid work - sweet :-)
