Magazine publisher mod

Hi, I have a very pricey but old magazine publishing script from a Swedish firm called Infomaker that is currently working on for the interview features and charts at www.pitchadjust.com. My problem is that it does not have any direct user management that works. So I would like to have this script modified with some acl of some sort so that I can add user types where they are allowed to do certain things such as post articles that are added to a cue for a super editor to check out prior to making it active on the site. This is step one. Later on we might need to re-work the whole shebang as it currently works very bad with Internet Explorer for example. But no budget for this at this stage so user management first... You will off course get access to the files if selected and I can even install a clean installation of it on some development server for you to check out alternatively I will fix some screenshots of what it looks like today. Thanks, Patrik P.s. Pitch Adjust today is using two different scripts, one for longer articles and one for short newsblurbs. Once the user management is in place, tghe newsblurb script will be deleted and the full cms will be used for all content again (we have had it for that in the past but because of no user management, we needed a temp fix to ease our daily work task). There is both author and client tables in the database that can be built upon. Currently I use a htaccess file for protection to login so a session login thing is needed in addition to the author modifications...
