I see, Jack: it is Yahoo whom you accuse of spamming, not the members of abcusers. These seem to operate in full public with their own names, many of them known to us as programmers or musicians, and volunteering their email addresses on their own websites, so that they do not seem to have any wish for privacy. (I always wonder though, particularly at Mudcat, whether posters of "contentious" messages are aware that these can be googled by anyone interested in the person, not in the subject.) Anyway, you can read "abcusers" without compromising your privacy.

The question remains whether we can hope for a common standard supported by the major ABC software and websites soon, also to become the Mudcat standard. It took me some time to tweak the "weird notes in the lower staves" of Nigel Parson's example into my abcm2ps.
