I agree with the idea of using Google Apps to provide emails to
arabeyes members, but
in the case, ther original emails of
@arabeyes.org may not be
accessible no more (it could be
substituted of course of that hosted on Google server).
in the case of
arabeyes.org giving a number of users
more than sufficient, and requiring one
step to verify the ownership of the website (either by uploading
a special webpage on the site or
changing some DNS records), and the second step is changing the
MX records to point to google
mail servers (all details are available when signing up in this
service).
this needs the non-profit organization to be registered in the US[1]
