I just received an email notifying me of activity in this thread. I thought I had that functionality turned off, but I'll check.
But that is not the reason I am posting this.
The reason I am posting is that I clicked on the link in that email, and it asked me to sign in, even though I am already signed in on this computer. I verified that this is the case by opening another instance of the browser and using a bookmark to go directly to the forum. It recognized me and did not ask me to sign in.
The reason I bring this up is that, like everyone reading this, I get a LOT of phishing emails, and they are usually disguised as coming from some site or institution with which I have some connection. However, if I click on a link (which I never do if I suspect anything), and if it is a fake (phishing) email, it will take me to some fake site and ask me to enter my credentials, thus stealing my identity.
I am 99% certain this email was sent by the new forum software, but I think there needs to be some adjustment to make sure it doesn't look like a phishing email.
[edit]I just checked and I do indeed have the email notification feature turned off, so it looks like there may be a problem with the new software sending out notices of new posts in a thread in which I have posted, even if I asked to have those turned off. I did see that others have had just the opposite problem, so I assume this is another one of those things that will eventually get sorted out.
