Dolphin Transtale

Hi, I want to translate my website in an easy and safe way and have the option of 2 or more languages to choose from. I created the language but it is a copy from english, how can I change the words of the website like in SocialEngine ?

thank you, 

sometimes it is easier to use google translate. did you look at that option yet?
