Hi, this may seem like a simple question, but i have never used dotnetnuke before.

 I have bought a business which includes 3 websites.  One of these websites is a dotnetnuke website, www.multilingo.co.uk.  I have the username and password for them but i wanted to know how i could get access to change it.  It also hosts a database of translators, which i want to keep as it is.  I do have a SQL server backup of this database but it is updating everyday with new translators.

 What do i do?

Is there a link to a video i can watch to help me with this?
