I am using this nickname which has some reputation and email.
How can I properly register with this name and not lose my reputation, question and posts while having more privileges and the ability to mark answers?

This question came from our site for professional and enthusiast programmers.
You appear to be unregistered on Meta. If you have registered at stackoverflow, all you have to do is: Go over to meta.stackoverflow.com(if you are reading this you are already there) and click Log in Select your open id provider and login using the same credentials you used while registering for the SO account, Meta (and any other SE site) will detect and merge your accounts.
Meanwhile if you are this person then you are unregistered on stackoverflow too. you need to go over to stackoverflow.com's login from the same browser that you have been using your unregistered account from, hope that stackoverflow recognizes you(because if you have cleared cookies or changed browser, stackoverflow will not recognize you), if SO recognizes you, you can select an openid service provider and login to register your account.
Finally if SO does not recognize you(you have cleared your browser cookies) then go over to Account recovery and enter your email address that you used while posting questions or answers. SO will mail you a link which you can then use to register your account.
To register click on your user name in the top bar and then click on the Register link in your profile. Then select a open id provider of your choice. (You can also click on the register link next to your username)
After registering, you will be able to login using the same open id provider to access your account. You can add multiple openid providers later on.
So basically if you remember the email id you used while asking your question you can recover your account and If you are already registered you can merge accounts.
