I signed the petition in your first post but this new one had passed me by until Alitalf mentioned it. Can I point certain folk I know on LJ at this post or cut & paste it for mailing list circulation? As some of this:

"inadvertantly" imposes potentially huge new costs on small publishers of pretty much anything (books, games, photographs... anything with copyright potential). (Specifically, it creates new registration and licensing requirements for any 'organisation' which licences any copyright material created by more than one different individual, or acts as agent for any such owners. So of course, that applies to authors' agents as well as small creative companies.)"

may well impinge on the ability of the TS to produce Seminar proceedings and suchlike
