I received an email "Marketo Support Awaiting Customer Input Reminder " this morning. I thought it is strange, because I am waiting now. I checked my case via marketo.com support page. My comment was not there. So I posted my comment again via marketo.com support page. No error was happen, but my comment was not added again. Finallyt, I tried to post 4 comment that is divided original my comment. It's OK. My comment is too long (almost 4K char) for this system??? ButI think that no message is not useful for users.
