The intranet! It enabled me to learn a lot more about CF, I was interacting with CF people without fear of cross-infection for the first time in my life. I discovered that there is such a thing as a lung transplant. I knew most of what a transplant involves by the time the Drs told me. Through facebook I have met more fellow CFers and transplantees who understand my health better than any of my "real-life" friends do. I also met Chris via the internet. So who knows where I'd be without this awesome tool!!!!
