HelloYisrael,
thanks for reply.
I just have spend 1-hour trying to understand where the import goes to?
a) PrivateMembersArea
b) Custom Member-Database.
Since Ahmad confirmed my statements and observations, that it is NOT possible to import data into “PrivateMembersData” directly, so it should be a “custom-member-data”, where the data is imported to. Do i understand it right? If not then i am very confused 
.
Yes, by using his own custom login-system i see no problems except the “PW-SECURITY”.
So my main question right now would be…
- Where does the import goes to? (custom database or “PrivateMembersData”).
- If it is the “PrivateMembersData”, how the import is possible?
- If the import realy is possible, how?
- The list of users in this case, are passwords included in this list? Or even the question, are passwords in this case needed?
Why i am asking if password is needed in this case…
I could actually see some sort of procedure whereby a site owner/admin imports a list of users with at least an email field.
Just an eMail needed?
- The import would automatically trigger a verification email to be sent to the user, who would then have to click a link/button/something to verify their email, and would then be prompted to enter a password.
Ok, a registration needs always at least an e-Mail + password ok.
But how the import can be done without entering a pw?
The only way could be to enter a temporary pw, or is this conclusion/statement wrong?
And the last question.
Why i can register a new member in using Wix-LogIn, without getting any confirm-Emails? This registered users can also use Wix-related stuf, right?
Damn, now i am really confused xDDDDDDDD
P.S: And then Ahmad mentioned some kind of HTML-solution, what? 
Could you please clarify, at least a little bit, or describe a little bit more detailed a theoretical process?
Why i am asking is, i want to understand this stuff.
Strange that i have more interest on any solution to this issue then the “post-owner”
