Judging by Hans Aberg's reply, there is perhaps a misunderstanding of
the purpose of this list.
It is for discussion of principles and requirements of LaTeX3, a major
new system, not that of refinements or bug-fixes to LaTeX2e.
So maybe, since the LaTeX3 Project Team does both of these, perhaps we
should change its description from:
Mailing list for the LaTeX3 project <[log in to unmask]>
Mailing list for the discussion of LaTeX3 <[log in to unmask]>
Or is that getting too long?
