I recently changed my email address for my account, as a result, I got a new member ID which replaced my old one 572967. I like to get my old member ID back because i have earned 3693 points with 4 articles posted. I hate to lose the points because they are quite hard to reach. Please let me know if it is possible. And anything you need to verify my membship.
