Bulk accounts or self-signups

[abasel]

We are wanting to use Sentora for our students to get exposure to creating and publishing their own sites.

I have two questions:

1. Is there an easy way to create a large number of accounts?
   
2. Is there a solution that we can use that would allow students to sign up for an account by themselves.
   

The latter option would be best (I did this a while back with zpanel but can't remember at all how it was done).
