// Twitterbox v0.4
// Post to Twitter and receive updates from within SL

// Ordinal Malaprop
// 2007-02-26
// Last updated 2007-04-18
// Free for distribution and use, but if you use it in something else
// I would like at least a mention.

// Full instructions and the latest version are always at:
// http://ordinalmalaprop.com/twitter/

//------------------------------------------------------------------
// Modifications from 0.3:
// - only works when attached to prevent boxes on the floor spamming you
// - keeps list of 10 most recent tweets, menu item added for this
// - option to show or hide your own tweets, showing by default
// - immediately checks for new tweets on startup
// - option to repeat the last tweet you made, useful for failures
// - checks for updates (separate script)

//------------------------------------------------------------------
// Edit these to your own specifications
// The email address you signed up to Twitter with
string EMAIL = "";
// Your Twitter password
string PASS = "";
// Your public RSS feeds (leave blank if you don't have any or you don't 
know what this means)
