How to create add and edit pages for content types beside to Administration In my drupal installation (Drupal 7) I have various users.
What I want to do is, I want to enable somehow my users to be able to create content their own, without using the administration page.

Lets say, user clicks on a link to create an article or blog without going to administration page. The linked page contains a form for the article/blog and the user submits that form. So has been the content created.

What is the proper way to do it?
Self development of forms?
How is the URL then built?

I have found something like that
how-to-create-different-panels-for-add-and-edit-node
but here the module "Pages" is probably used.

It would surprise me that something like that does not exist.
If it's simply a matter of using the non-administration theme for node edit pages, there is a setting at admin/appearance, at the bottom of the page, for setting the administration theme. It also includes the following check box: "Use the administration theme when editing or creating content". Simply uncheck this to use your non-admin theme for node add/edit forms.
