I'm working here, soon you should be able to download my Sibelius Music files straight from here.

Links

here are some links to a couple opf good Tablature sites:
MXTabs Guitar, Bass, Drums. A public tab swopping place, so most songs are tabbed by amateurs. but it's pretty good none the less. also has general playing lessons, music reviews and forums.

The Offspring Guitar, Bass and Drum Tabs for The Offspring songs, the website also has their lyrics and other band info. but very few drum tabs, not all their songs are tabbed for all instruments.
