<p>The analysis of the situation revealed that I accidentally set up two accounts one for CrossValidated and one for Quant forum.</p>

<p>Then the Quant login propagated to CrossValidated automatically as a convenience provided by the system. As a result I thought all my reputation was lost. In reality it was still on the other account.</p>

<p>Thanks to admins they merged my accounts by following the steps in the comments above.</p>

<p>All is good now.</p>
