Music notation aid

Yesterday I combined two songs from my church's hymnbook in a voice/violin arrangement. It took me about two hours using a great website I just discovered--Noteflight. It is a user-friendly online music notation tool that will store versions of your piece, play the different staves in a selection of music instruments, and insert text wherever you need it. Oh, and it's free! I highly recommend this if you have any composing needs.
