Giving by text is hands-down the easiest way to give. Simply text CATALYSTCT and amount to 77977 (e.g. CATALYSTCT 200). If it's your first time, you'll be prompted to register before completing your gift. If you've given before, you can give immediately without having to re-enter any of your information. To give subsequent gifts through text giving simply text the amount you want to give to 77977.
