Sorry forgot this one, mail notification settings says
"Send an email if a new chat message arrives and I am not online"
And I receive one even if I'm connected (but not on same tab) which does not match option configuration 😉

won't do anything if the array is empty

I guess the problem is that latest release of template.js does not allow another the loop inside a template, then I have to declare that loop in another template and include into my item.tpl

Updated my post, thanks.
