I've got a whole list of stuff I've arranged and tabbed with Harmony Assistant. I usually save a file as PDF by using the "Print score" facility and then selecting the Save as PDF option (I use a Mac, by the way, so it might be different if you use a PC).

I then upload the PDF to my website and make a link on my "tabs" page. You can see examples at:
my website tab page

Seems to work OK - sometimes the thick/thin vertical lines in the section breaks in the score look a little weird but, apart from that, it seems to be adequate.
