Deactivate /Optional Email for Registration


Hello, I want to use rocket chat within a website as a customer support chat/ Sales Chat etc. Similar to the common chat which can be found on many websites. (Like facebook messenger)

So I want that a user only needs to provide a name and only if they want an email. I am writing a little API in node/express, which alredy creates users and logs them in. So the next step would be to call the iframe (haven’t figured that out fully). However, currently a username and the email must be unique.

For the username, I just append a UNIX timestamp as suffix and I am sorted. However, since I want to leave the email optional and a sufix or prefix will create a nonvalid email I thought it would be great to tell rocket chat that emails are only optional - is this possible?
