I totally understand the challenge to getting things done in the context 
of TDWG being a volunteer organization.  But that isn't the problem with 
the DwC class proposals and the RDF Guide.  In both of those cases, 
unpaid volunteers DID put in the many hours of work necessary to do the 
writing and achieve consensus within a working group.  The problem is 
that those proposals have been held up by many months because nobody has 
made administrative decisions necessary to move them forward.  We don't 
need a grant or more volunteer hours to fix that problem.

The case of fixing the more systematic problems with vocabulary 
management is a little more complicated.  But again a group of 
volunteers put in many hours to assemble recommendations of the VoMaG 
report.  Somebody needs to act on those recommendations - accept, 
reject, appoint a task group to work on a draft standard or whatever.  
Here as well, the problem is lack of action, not lack of volunteer time.
