<?php
$usernames = "immaginoteca urbanohumano ecosistema"; // Pull from accounts, separated by a space

$show = 1; // Show username? 0 = No, 1 = Yes.

$prefix = "<ul id=\"twitflow\">"; // This comes before the entire block of tweets.
$prefix_sub = "<li>"; // This comes before each tweet on the feed.
$wedge = ""; // This comes after the username but before the tweet content.
$suffix_sub = "</li>"; // This comes after each tweet on the feed.
$suffix = "</ul>"; // This comes after the entire block of tweets.
