I tried following the instructions provided by http://www.pumpkinpirate.info/flattery/
which did not result in a toolbar. The email address provided does not work either.
My wife found the answer that works. I could not get along without her!

Go to the Menu
Window> Preferences> Extensions>
Click the Install Extensions... button
Browse to your downloads folder
Select the file
Flattery_v1.0.2.rbz
Click the Open Button
Follow the usual "Yes, OK, I Agree" type options.
Now Flattery is correctly installed and you will have the menu bar you expected.

I Hope this helps you too!
