Hey guys — thanks for raising this, and sorry for the hassle it's caused.
First, the important bit: this is not a scam or phishing, and your accounts are safe. Those "confirm your email" messages were being sent out by our own forum by mistake — a glitch had it firing off confirmation emails over and over, even though none of you asked for anything. You didn't do anything wrong, and there was never anything you actually needed to click.
I've fixed it on our end, so they'll stop. If one or two still trickle in right after this, just ignore them — they were already on their way before the fix went in. Next time you open the forum your address gets squared away automatically, and that's the end of it.
And @ianfontinell nailed it: your email here is tied to your main account on the site — there's nothing to set or change on the forum side, so anything asking you to "verify" it here was never something you had to act on.
Thanks again for flagging it, and for being cautious with those links in the first place — that's exactly the right instinct. If anything else looks off, give me a shout.
