we are currently porting our K2 website to K3.
On our site we have a “team” page which for each team member provides a link to our contact form with the username as parameter to contact the individual team member, e.g. /contact/john-doe
A main reason for the contact form is to not have the email addresses of users written on the website. So I don’t think it’s a good solution to pass their email in the URL (and I also don’t want to pass it via POST etc.).
So what unique identifier can I use in K3 to pass to the user to the contact form?
