hiding sidebar for general users

Hi All, I'm a complete newbie on pier, although I have some experience on general seaside, so, excuse me if I ask siple questions... I didn't find them on the list, so, maybe there are too easy. I'm trying to make the website for may company, and of course, I don't want it looks like a wiki, I want it looks professional, like lukas page (http://www.lukas-renggli.ch/) or "kamikaze" page (http:// kamikaze.seasidehosting.st) After this long introduction, here is my first question: How do I hide sidebar for general users, and allow it for "admin" users? I can took off +sidebar+ div from "environment " template... but then I don't have the commands for admins neither. And here is another dumb question: Is there a way to have "childrens" (from a children component) in a specific order?
