Modify a plugin userbase for wordpress

Hi,

I have a free plugin for wordpress who replace user original database. I would like to modify some stuffs.

Modification 1:

Currently wordpress don t allow to register an user who is already present in another subsite.

So, with this modification, Admin must be able to register an user if an user is not yet registered or if an user is already present in the database.

So script is :

- admin fill new user page (already exists) with new contact information and can tick or not send welcome email with password (must be added)

- if user is already registered and email not required to be sent => just add users in subsite without specific action or message. Password to be used for subsite is password already present in database

- if user is already register and email required to be sent => add user and send welcome email with his password already registered in database

- if user is not register in database : register user and create automatically a password and send or not a welcome email.

Of course, possibility must be add to be able to send this welcome email with password anytime even after a user has been registered or added (just need to tick a checkbox in userpage "send welcome email with password").

For security reason, current wordpress username must be email of user and not be able to be modified by admin (otherwise, he could access another subsite by changing email).

remove possibility for admin to change manually password of an user.

Modification 2:

Synchro address info from an ecommerce plugin to userbase. ecommerce plugin creates form in current user page, so just need to synchro.

MAdd appointment remind in user page. My appointments come from an appointment plugin (nothing to add or remove) already present in original user page. so just to transfer the function the plugin
