I have a team member who had a trial account and now I am trying to add him to our team account. Unfortunately, every time I send him and invite, he instead gets prompted for payment information. Please help

Hi,

I would like to invite students in a class I am teaching, so we can interact using Vertabelo. At the time I created my account, I was asked to input a list of student email addresses, if I had such a list. At the time I did not have the list, but now I do. However, I can no longer find or access the form that asked me to input the list of student email addresses. Is there a way to do so after creating my account?

I have 102 points in my accounts. how can i redeem it to upgrade it to the premium plan.

Recently when I try to open your website, most of times it returns errors.For example,"bad request" or "can't get access".

I have a payed account and my position is in mainland China.

Please help.Thank you.

Is it possible to restore a deleted model?

I used the basic trial period which expired

I want to use references between two models

For the following CREATE statement

CREATE TABLE tst (
     id int,
     primary key (id)
);

postgres infers, that since id is primary key, it should be not null and ends up creating following table:

| Column |  Type   | Modifiers 
|--------+---------+-----------
| id     | integer | not null

In vertabelo, while importing model form SQL, the not null modifier is not added and I get "Primary key column can't be null" error.

Would be very useful to be able to export a higher resolution PNG of the database schema. Could it be possible to specify the resolution of the PNG to export?
