I've been trying to support a couple of petitions for some days, but as soon as I go through the process, I get a message that they don't support my browser... and go on to recommend that I use one of the browsesr that I'm already using! I don't know whether I've duplicated, trebled or quadrupled my signatures: I suspect they haven't accepted any of them, because they are so anxious to persuade me to download the Google Chrome program that I'm already using. I'm certainly not receiving the usual "thank you" and to please "let zillions of friends know that you have signed this petition,," Perhaps I should start a petition suggesting that Change, org set their own house in order... get their act together, and stop wasting our time by their own inadvertence.
