BOTH...
But more so for the social aspect of CF. I have hardly ever been in contact with other CFer's and when I was in contact with others, they were a lot older than I was. I came here 2 years ago, in college, when I had gotten a taste of what CF to CF friendships were like. I had met three girls at my college with CF and it made me "hungry" for more CF contact. I had always wanted to be in contact with others, but wasnt aware how I could. So this was and still is the perfect outlet for me.
I have also learned a whole hell of a lot from everyone here. I have learned how differently certain people deal with CF and how the cases vary so much.
