\opening{Dear Mr Chan,}

We are writing to enquire about the possibility to move the latest
Aegir CMS code derived from Nadmin Studio under the GNU General Public
License (GPL).


The Aegir CMS Business Community represented by multiple companies (see
enclosed appendix), most of them former Hong Kong Linux Center (HKLC)
clients and partners, decided to take over the development of Nadmin
Studio under the new name Aegir CMS.


The GPL would enable us to continue the development of this product and
Linux distributions to utilize Aegir CMS, spreading the Aegir CMS/Nadmin
Studio Community. Moreover GPL would enable more volunteers to get
involved in Aegir CMS development, making the product better for also
HKLC's clients


HKLC would still be recognized as the original author of the
application. In essence, Aegir CMS would be free, widely spread
advertisement for HKLC's development services.


Changing the license of Aegir CMS will not will not take
anything away from HKLC, and brings the possibility of large number of
additional business by paid customization work and projects.
HKLC's name will remain in the application, and so users are
likely to ask there first for any professional services.


If you agree with this licence change, please send a confirming email to
nadmin-dev@midgard-project.org.


We are looking forward to hearing from you.

\closing{Sincerely yours}
