Yes or you can go to admin panel and search in language keys for the words you would like to change

go to
admin/settings/language keys/
Search for strings
Look for: _________ *press search*

when
searching for _____(powered by) also (copyright) that should change at the bottom for all pages of DOLPHIN ..
dont forget to refresh browser to see the change ... good luck !

Under settings there is only Languages Settings not keys, I'm I ok?

when you get to language keys at the bottom there is something like this
******************************
searching for : _____________
********************************
where its underlined is where you put : *powered by*
then it will show you powered by a few times and then you change where you see DOLPHIN and PUT your SITE name.
