[tdwg-tapir] Abundance data

Mon Dec 1 14:59:31 CET 2008

As the average TDWG mailing list is not exactly overloaded with posts,  
how about consolidating TDWG's mailinglists into just 3?
An announcement list for TDWG business (tdwg+process), a technical one  
(TAG,GUID+TAPIR) and just a single content one.
This would probably also help to avoid duplication of efforts and to  
produce more consistent results across the subgroups.

Just an idea.
