Correct Spellings

I am wanting to correct spellings on some places in the interface...for example...on the Admin side of dolphin...the Dashboard has

Admin

Clear Cache

Users

My Mails..

Where do I need to go to change My Mails to My Mail?

Thanks

Settings/Languages Settings

_adm_txt_dashboard_mails

Most of the admin text will you find if you search after _sys_adm or _adm
(apart from modules)

Thanks for the information. Appreciate it greatly.
