Well it's March 14 again, which means it's Pi Day! So obviously, you should donate to your Pi Chapter now! Check out this page for your options: http://www.pizetes.org/donations/
Also, if 314 alumni donate to RPI today, two trustees will donate $25K each to the Annual Fund. If you have extra disposable income after donating to the Pi Chapter, why not send RPI some money too? Information is here:
