New user registration activation timeout? Does the "Activate your account" link, in emails sent to new users, have an timeframe for expiration?  I've had a few of my users run into a "Invalid verification code" error when clicking on the link, after waiting a couple days. If I resend the email, and they click on it within a few hours there's no issue.

I've looked through the docs and posts here and don't see any reference to one.  If there is a default expiration, is this something I can override?

Thanks!
The verificationCodeDuration config setting is what you're looking for.  Defaults to 24 hours.
