So I tried using the contact form a few times. First I noticed that it tries to open an email client, which I prefer not to use. Second - and perhaps more important - when I try to send an email to the address in the mailto link, I get an error from the mail service saying “The group commonvoice.mozila.com does not allow posting through email.”
I’m not 100% sure, but I think that, basically, the contact form (or email for it) might be trying to make a post in this forum, or a similar one, instead of sending an email?
