Due to graph API changes made by Facebook in April 2015, the ability for the BOINCStats Facebook app to post to users' time lines has been removed and there is no workaround.
Over the years the app has fought to keep up with the various API changes made by Facebook which have often broken the app.
I have therefore sadly decided to remove the app from Facebook by 30th June 2015.
Thank you to all those that used the app, suggested new features and reported bugs.
Cheers,
Neil.
