i need to chance the domain name and as i figure that im changing the access name right by going into admin panel - general admin - configurations and there at the top domain name and then in the box is bb.phpbbweb.com.

so my question is what am i changing ?

lets say i whant to change it to have the letter "abcdefg" somewhere in the domain name where whould i type it ?

infront of the "bb.phpbbweb.com or after it ?

what should i write there to change the domain name so i can have "abcdefg" in it ?

thanks
