hey. i was wondering if there is a way to have a webpage that would stay the same. but have another document hosted which would be like the database and parts of the main site would be like the mail merge. so it would read certain parts from the other document...

or like a way to have a site, but the writing which i would like to change is linked in from another html(? ) document. so when i change the html with the wiritng. the main site loads the writing from that document so i can easily change what is written without editing the html for the main site.

sorry if its confusin ill try and explain more just ask about wahat you dont understand.

thanks
