Questo script legge le versioni più recenti della pagina corrente usando le API di Mediawiki, e le mette in un box sulla sinistra, sopra al box "navigazione", dopo la pressione di un pulsante.
Nel box vengono elencati gli utenti che hanno modificato la pagina (con un link al paragrafo modificato).
Prima di ogni nome viene inserita l'ora della modifica che, se cliccata, apre una finestra in cima alla pagina mostrando le modifiche rispetto alla versione precedente.
Fermandosi con il cursore un paio di secondi sul nome dell'utente, verra' mostrato in un tooltip l'oggetto della modifica.
