We need a "Daily FReep," somewhat like the 60-Second Activist. Get a few volunteers together (good mix - different religious outlooks, political parties, etc.,) to take suggestions, decide on a day's items, then let loose the dogs of email, telephone calls, and sundry activism. For instance, I like to print out articles and leave them in the bathroom stalls at work.
The Alliance for the Separation of School and State is an excellent site that every FReeper (and their closest 500 friends and family) should know about and support.
Life Dynamics Inc. (pro-life) is another.
And on days when nothing overwhelming is in the pot, we fall back to emailing Trent Lott to tell him what a pansy he is.
