Editing text for translation
Translating text via the Drupal interface can be pretty tedious to say the least. This is not so much because of Drupal, but because of page reloads every time a string is updated. There is a much better way to translate strings into a different language, namely editing PO files with a PO editor, and then importing them into Drupal.
A full guide on how to translate Drupal Core or modules, using the above-mentioned technique, can be found here.
