ISPConfig is GREAT - well done - very goood work.
But there is on thing that really should be changed:
The username web1_username is not really a good Idea.
I think firstname.lastname@example.org
would be a good way.
YES I know, if the domain name changes....
BUT users are accustomed to user their email@example.com
A Linux account with firstname.lastname@example.org
could be renamed to
username and this might cause some troubles....
Thank you for thinking about it.
