I have not been receiving emails from LC for a while. Earlier this year, I was getting the same message as many users that LC emails might be phishing. I do not know if anything was done about this issue. I continued to get this message for a few months and now any emails from LC have stopped. Even though I have my preferences set to receive an email when I get a PM:
I do not get them. I use gmail.
ETA: I also get an error when clicking on the help desk.
