[Uni-verse] D2.2 section: End user perspective on functional specification Architects Study

[Lauri Savioja]

Hi All,

I agree completely with Ludde! I remember writing a complaint about
the same issue in mid-March. After that I concluded that we want to
have the original version for some historical reason although the text
is not valid anymore. The work described in WP7 aims to the goals
as presented by Ludde!

Regards,
	Lauri
