Some of the ones I've joined lately:
-We Want to Get Stranded on Fiji Island: for girls who are fans

of the Fiji boys (like anyone is surprised I'd be in this hahaha)
-I Hope There Are Crocs In Heaven...A Tribute to the Crocodile Hunter
-Blackouts Are Real!: my friend Vicky made this and I don't know why I am a member b/c I haven't gotten blackout drunk in a long, long time but since I am the "Fiji Rep" I feel obligated to remain a member
And my personal favorite just b/c it is so dorky...
-Tigers of the Corn: this is actually what the name of the Mizzou alumni group in Nebraska area (which of course I am now a member of), they seriously could have picked something better than a name that sounds so much like "Children of the Corn" (horrible, cheesy horror movies) don't you think?
