exJello is a JavaMail provider that connects to a Microsoft Exchange server (actually, it uses the WebDAV interface exposed by Outlook Web Access). It is designed as a drop-in replacement for the standard POP3 and SMTP providers. This allows you to send and receive messages through your Exchange server in situations where a POP3/SMTP interface is not available (through a restrictive firewall, for example, or if your administrator simply does not provide a POP3 or SMTP gateway).
MemoVerse is a tool that helps you memorize Bible verses. It features a user customizable Bible verse profile and a "Practice mode" that lets the user enter the missing words in the verse, keeps track of the difficulty level achieved on a verse-by-verse level, prints verses on flash cards for offline study, allows one to memorize an entire passage or parts of a verse, and provides a timer that keeps track of how long it took to complete a given verse.
