Yep. If it's not already asking you for an email address at this point, you should go to My Account and provide one (eventually, you'll be able to fill in other stuff there, too).
That's where the rubber hits the road. Once you give us an email address that we recognize and demonstrate that you're (one of) the people who can actually read email there, i.e., by clicking on a link in a message that we send to you at that address, then we're in business.
You can do that; we like finding out your other email addresses, and, once verified, they'll be added to your account like any other. But until we get an email address we recognize (e.g., one that you've given us at a meeting), we have to treat your account as if it were for some random person we don't know.
That happens. Come to a meeting! We'll talk about it.
The verification email we send includes quotations in order to make it easily distinguishable from any other such messages you might receive due to, e.g.,
The quotes are randomly selected and it's highly improbable that someone will guess in advance which ones we'll use, or that a second verification message sent to your email address will use the same quotes in the same order.
Thus, if you see the correct quotations, you can be pretty sure this is indeed the message you should be responding to.
Conversely, if you see a message somewhat like what you're expecting but with different quotations, then you should ignore that message and especially not click on any links there.
If the email was indeed a genuine verification email sent from here due to someone else trying to set up their own account but giving your address by mistake, nothing much. In general, clicking on the link in such emails does nothing unless you are signed in to the same ID provider as you were when you had the email sent. Meaning if you click on a link that's actually for somebody else's account, you'll be prompted to sign into his/her ID provider account, which you (most likely) won't be able to do, and that will be that, i.e., nothing will happen.
If, however, the email was faked from somewhere else, i.e., from a spammer, then all bets are off and it's just as if you were to click on a link in any other random piece of spam that you get. Which is why you should generally not click on links in email unless you're sure you know where the link is going. This is not a problem if it's a plain-text email, which ours are, but for rich-text email you can't just look at it — in a web browers you can often do right-click "Copy link address" and then paste that into a Notepad session and see what you get. If it begins with https://s.kcdems.org (our site) then it should be safe to click. But this can be inconvenient to do. Which is why we provide a cut&paste alternative, where you control the website you're pasting it to, and can thus be sure that it's here.
