Pass variables to Registration page
Let say, I have a site (not a NodeBB site) and it has a newsletter form where users can subscribe by filling in their names & email addresses. After they hit submit, I'd like to redirect to the the forum site (Registration page).
Is it possible to pass variables (eg: email address/username) to Registration page via query string?
For example, https://email@example.com
What I want to achieve is to since users have filled their information earlier, albeit on a different site, the Registration form should have a prefilled form (ie: name and email address).
