change phplist into oempro

We got a PHPlist newsletter system but want to change this into much better oempro system. the website is [login to view URL] , here you can see what we got, and this must be replaced with similar options, but than with oempro as bbase. means adding the newsletters, import the users for it, and use the phplist template as oempro template 2 more options must be added, so instead of 6 newsletters list we get 8.
