If you're in the college facebook, add me!! Search for "Rebel Fornea", I'm the only one, I promise
If you're in high school or college (or if you're an alumni who still has their college email address) or if you're a college professor and haven't heard of this yet, go to www.facebook.com or www.thefacebook.com. Either one will work, they now have both addresses.
Keep in mind: you're supposed to use your real name, not 'Reynard the Fox King' or whatever. Nicknames in quotation marks are acceptable.
Anyway, facebook is really fun. It's hard to explain why...it's just really addicting and fun and I promise you'll like it. And even if you don't, you have nothing to lose, since it's free.
