How do I change the user name and password from my FCKeditor intro panel?

Hello Guys,

nice to meet you. I have a great problem.

Some years back, in 2008, a web designer created a website for me, andreas-krauss.com

He also build the site manager belonging to it. And because I asked him back then, he made certain it was very simple and had only the functions I needed at the time, for which I am still very grateful.

But unfortunately, there's no function in the site manager for changing the administrator name, the password I sign in with into my site manager or to add new administrators, should I need them.

This has become a great problem, because that older designer who originally build the website seemed to vanish for several years or at least I couldn't even contact him via the link in my site manager.

Several weeks ago, I hired another designer for updating my site manager and the website. It was an indian worker, not an American.

Originally, prior to me hiring him, he promissed to finish the whole project in 4-5 day. That was 19 days before, even though none of the tasks were changed and the whole project was outlined and detailed for him even before he bid his fee.

Any way, in order for him to be able to work on my website, I gave him the unchangeable password and user name.

But now not only doesn't he do the promissed whole work I detailed for him before picking him (for example, I am still waiting for him to equip the site manager with a function that generates PDF files from each sub page), but, far worser, he's begun to delete the content of several sub pages (WITHOUT my permission or even my prior knowledge; I only found out about it today, when I rechecked his progress.

Since I made no backup, that content is likely gone forever.

Now I want to change the user name and password of my site manager, until this situation is cleared.

But I don't know how to do it, because there seems to be no buttons for doing so.

But there must be a such function in my site manager. Can you tell how I change my site manager user name or password? And how to add additional administrator accounts and limit them so that the problem I'm wrestling with right now doesn't happen again?

Best wishes,
Andreas
