Hello,
i have some websites with some communities...
WIth Mightysites i would like to have a central database for the users by all my communities...

- Main Site: site of my agency
- Slave Site 1: Community 1
- Slave Site 2: Community 2
(etc.)

I have some questions:
- the database recognize from what website any user is registered?
- Mightysite works with Pay plans? All my communities has a payment membership
- If Mightysite works with Pay plans... if a user pay his membership in the "Community 1", when he join to Community 2 he pay too? Or the payment is only one?

Thank you!

MightySites can help to share users: 2 slave sites will load users from database of master site, so all 3 sites will always have same all users. Any user-related action on any site will affect all sites (no matter where user is created/registered/updated/deleted - all sites have same users).

If PayPlans uses native Joomla database layer for all database queries - it will work.

No more options are available, just 3 sites will have same users loaded from users tables of master site.

You can create a separate usergroup for each site and configure it to be selected as default usergroup for new users, so you can see from which site the user was registered.

Thank you!
If i create different user groups, a user can be in 2 or 3 differents user groups, if he pay his membership in 2 o 3 websites?

Once a new user is registered in Joomla he is assigned to one default usergroup.
Next you can manually assign user to multiple usergroups.

Yes, please check this case study - it's the best and most common usage practice:
