hello.
sorry for posting [OT] to this list, but i fear the OT-list will not reach the person in charge.
it seems like somebody has subscribed pd-list to the googlegroups (either directly or indirectly, i don't know), since i (as list-administrator) get repeated rejects for pd-list digests from googlegroups.com.
whoever did it, please undo it. before you subscribe a non-person (e.g. another mailing list, an archive, a groups-system,...) to a mailing list you should be aware of al lthe technical and social implications of your doing and make sure that a minimum of problems is likely to occur.
on the sovial level: many member of this list have repeatedly expressed there concerns about unknowingly posting to whatever groups. even though the pd-lists _are_ public and there archives _are_ publically available, this is not a realy excuse to publish postings of an author without them knowing.
on the technical level: mailinglists often do not stack very well (especially those with restricted access), as this is not what the developpers of the list-software (usually) had in mind. problems range from bouncing emails via mail-loops to ... you ought to know which software is used on both sides and be aware of any problems that might arise by combining these 2 softwares. you ought not think about subscribing a list before these problems are sorted out.
