Feature / Enhancement Description

Add Parse Server API Mail Adapter to list of mail adapters in docs.

• The main issue this adapter solves are localized, templated emails for password reset and email verification.
• Adapter allows to modify the form links to attach the user locale, which allows also the forms to be localized or pass any other arguments to customize the form.

You could add this to the community section on the website.

It would be the only email adapter on there, is that because we just didn't add any of the existing email adapters to the list yet?

[TomWFox]

I think the section has just been neglected, there is a My SQL adapter on there. You could wait until we have a new page for it and then we could add all of the adapters.

[mtrezza]

I'll wait for the new page then
