Main Admin Power

OK so when I created my website I didn't know how to change my name so I just created another account. Well now I want to switch the Main admins power to my real account so that I can delete the admin account and have a 2nd admin without worrying if the Admin is going to betray me and change my password and/or delete my real account account

Bassically I want someone who can...

Admin powers go to > Icyoooppplaa on my website then delete the real admin...

Sorry If this is confusing cause I really don't know how to explain it any better. If this is possible and if a URL is needed then just click my homepage on here

just make a new account and make it an admin of the site thats it

erm If Can make a new account and make it admin

...-_-...nvm just lock this...
