To your sister-in-law:
A couple of my friends are longtime Freepers, although they haven’t posted in quite a while because of life & time constraints. I got curious, and I lurked here for three years before signing up to post a year ago. It’s like having a home among like-minded folks. Freeper humor is the best, and it’s a kick to scroll down a thread, knowing someone will have voiced exactly what’s on your mind.
Lurking is fun, but getting involved is even better.
Well, I'll be darned. Something else we have in common :-)
