Deleting current domain name...

Hello,
I bought a domain name for my forum in October. I've recently decided to change the forum Name/URL.
I know that I have to pay for the new domain name again. Do I just delete the current domain name and then put in for the new one? Or do I just contact Typlo to do this?

Thanks for any help. I just wasn't sure how to go about doing this and would like to get it done by Feb 1st.

You can delete it in the admin panel where it says Domain Name or you can contact Typlo.

Okay so either way is fine then. Thank you.
Then after it's deleted and back to the original domain name, I can just purchase the new one?

You can.

Thank you so much!
