If it's any consolation I had exactly the same problem - the email address on my account was no longer valid so I did not receive the email concerning the password change.
I did as some of you have done and became a newbie (PaulRlost) took David's advice and contacted Admin. I was up and running within 24 hours. Tedious I know but quite straightforward.
You don't have to be registered to use the link but you do need to tell them your user name and email address you want to be linked with it. They will then add the email address to your profile and send the new password to that address.
The password change was a security issue. Here is the message from Verticalscop (site owners) about it:-
Notice of Data Breach
You may have heard reports recently about a security issue involving VerticalScope. We would like to make sure you have the facts about what happened, what information was involved, and the steps we are taking to help protect you.
On June 13, 2016, we became aware that February 2016 data stolen from VerticalScope was being made available online.
What Information Was Involved?
Community member usernames, email addresses, hashed passwords, community userIDS, community website, and the IP address the username originally registered with.
What We Are Doing
We are in the process of invalidating passwords of all VerticalScope user accounts. We have posted a site security notification on each site updating users on the potential risk to certain accounts, the password reset and steps we are implementing to improve security. We are in the process of implementing stronger password rules (passwords now require a minimum of 10+ characters and a mixture of upper- and lower-case letters, numbers and symbols) along with automated account password expiries to encourage more frequent password changes. We will remind our users to use good password practices (not using the same password for multiple online accounts and using unique strong passwords). We are in the process of implementing additional safeguards to detect, alert and mitigate any future brute force attempts, and have notified our third party vendors that interact with our various forum API's of the February breach to allow their own security teams to investigate. We are continuing our investigation and will be collecting information to provide to the appropriate law enforcement authorities.
VerticalScope is taking steps to strengthen account security. We were already using encrypted passwords and salted hashes to store passwords, and our new password controls are intended to further strengthen user security. We are taking steps to investigate and test new encryption and security technologies to further protect our users.
What You Can Do
To keep your account as safe as possible, we recommend that you regularly change your VerticalScope community password, and that you use a unique password for each of your online accounts. Using the same password for multiple online accounts significantly increases your chances of being compromised. Even though the passwords stolen in February were hashed, we recommend that if you were using (or are currently using) your VerticalScope community password across multiple online accounts, that you change your password for such other online accounts. We encourage you to regularly review your accounts and report any suspicious or unrecognized activity immediately.
