I usually copy & paste a recipe into this box. Then I cut and paste the title into the Title box. Sometimes I tweak it a bit if I want to add some history or perhaps some more explanation. I was doing that today and and finished and clicked Submit New Tread and it immediately popped up the Login screen.

First click the backup button in the left hand corner of this screen, and you will see your entry. Click on the main text box and do a Ctrl A, then Ctrl C (you can right click the mouse and click Select All and then right click again and click Copy if you prefer, but once you learn these hot keys they are faster and I think you will like them). Login and then click Post new thread. Click in the text box to get focus there, and then do a Ctrl V (right click and Paste). Your text will be there and all you will need to do is type in the Title.
