Hello everyone,

I am new to the world of Odoo (minimal knowledge) and I want to integrate this solution for multi-company use. I installed version 10 on Ubuntu Server and everything seems to work properly but I wasn't able to configure the ERP for multi-company use.

Here's what I did:
- Configuration -> General settings -> Check: Multi company - Manage multiple companies, Multi-currency: Allow multiple currencies -> Uncheck "Share partners to all companies" and "Share articles between all companies".
- Users -> Companies -> Create two S1 and S2 companies with the YourCompany parent company (created by default).
- Users -> Users -> Create two users U1 (S1 Current and authorized company) and U2 (S2 as Current and authorized company).

Problems / Questions:
1) Users U1 and U2 can create companies. How do I disable this feature (disable the Company menu under Users) ?
2) In the Sales app all customers are displayed, I want to show only the S1 company customers, How to?
3) When you install the "Website Builder" app and go to the URL http: //myoddoserver: 8069/ the site of the parent company YourCompany is shown by default. Is it possible to have a site for each company and that the default URL http:// myoddoserver: 8069/ redirects to the login page ?

Thank you in advance for your answers.
