However, if your regret is pure fiction, don't bother. You're just wasting everyone's time. But if you are genuinely interested in contributing something meaningful, go right ahead.

Please use your real first name, not your Internet user name. Your anonymity is assured because I can only see an e-mail address if you type it in yourself.
