SYnchronizing subscribers with registered users

Hi,
On our website we use the Alo EasyMail Newsletter to satisfaction, but we missed the synchronization of user/subscriber data.
1.New users (members of our association) will only be synced with the Alo subscribers list if the admin presses the “Import from WP members” button.
2.If a subscribers’ e-mail address changes, Alo will not automatically follow
3.If a member is deleted, Alo will not delete the subscriber with it.

I’ve made a plugin, that takes care of this, as I did not find another solution “out there”. Anyone interested can contact me: [email protected]
