lostland is the absolute best challenge community out there. It's extremely well moderated, EVERYONE is friendly, the challenges are do-able, enjoyable, and yet still challenging enough to earn the label challenge.
You won't be sorry you joined, especially if you join TEAM OTHERS. 8D TEAM OTHERS is gonna get you so you better HIDE YO WIFE and HIDE YO KIDS and HIDE YO HUSBANDS too!
You should probably like LOST, of course. ;)
Tell them CELLEY aka CAPTAIN BUNNY KILLER sent you!
