From FormatBlue Software:
Text Formatter Plus formats email and newsletter or ezine text to your specified line length. You can right and/or left indent text easily, set a left margin and check that the web addresses you've used are correct and functioning. It allows you to save pieces of text you use regularly and then easily insert them when required. When you want to edit someone else's article that has already been formatted with hard returns, the program will strip the hard returns so that you can start work on the text immediately without wasting time.
