Should have thought of this yesterday.
Next time, as you add favorites, edit a “draft” email to yourself that just sits on your server in the “draft” folder forever and ever. If you can get to your email server (webmail or some such) you can get to that “draft” folder and find anything in it you wished to keep. This can be done from any compooper, even if you’re visiting a friend’s house.
What a wonderful idea that is! Thanks! I’ll do that next time. (Not on this one, though...)
