I used it yesterday to send her an email...
What it's supposed to say, after i send the email, is something like:
We have sent your email to ilya. You will now be returned to the thread.
But in this case it says:
We have sent your email to $sendmailto. You will now be returned to the thread.
which means the variable wasn't executed.
i'm a programmer myself
i hope the email was sent though, and it's just an error in the template..
