tidbits: you can post little factoids about yourself in your profile. your tidbits are shown randomly every time someone views the page, so be sure to post a lot of them!
thumbnails: a thumbnail is a small image, usually smaller than a square inch. you profile thumbnail almost becomes your nametag for people who look at lots of information quickly
linking to the outside: ever find, when you're writing a post, that you want to link to a common site, but don't want to go all the way over there to find the actual url? let avalantern do it for you! if you write a link, using markdown, simply mention the common site in your parentheses. for example: (the beatles) [itunes artist] (tiananmen square) [google images] (neil young) [amazon] (eternal sunshine) [imdb] avalantern will then convert that into a link, and you'll never need to leave avalantern!
friends: don't really care about all those random posts by that guy you don't like? you can view only posts from your friends by going to recents / friends
