Ok so I followed these instructions religiously and I get a new tab i.e. View | Edit | Track | TRANSLATE. I get the other language link (in my case Francais) display at the end of the article which when clicked on did toggle between the translations the first time but no longer. I get the ability to position the Language Switcher in Blocks but it doesn't show in either admin or user.
To be honest I was hoping that I would simply get English and French radio buttons and a module would do the translation for me (as in Google Translate)
BTW. Perhaps Step 7 needs a little more explanation as the it is presented as page not a downloaded file and in Step 4 I believe you want to go to simply Configuration/Language.
