H everybody!

Is it possible to create a link which redirects directly to an entry form such as new Discussion entry?
Background: I want to design a landing page for the users to view suggestions made by another user. If they want to make a suggestion by themselves, I want them just to hit a Button and there it is: The Form to make a suggestion! They just have to type Title and description and hit OK and that’s it. No detour via the folder.

Another question:
Is it possible to hide the navigation panel automatically in a normal folder, like I can do it with a landing page?
