¿How to enable a menu item for users who visit my homepage, can add your own properties through the homepage?

Hi.
You need to enable the me menus in the backend.
its already installed together with the components , you just need to enable it.

Thank you, Jay.
There is no menu ME in the backend, which module should I install to my show?

You have to create a new menu item of type .... There are 4 differents types of item relationship with ME.

Thank you, jrariasf.

What I want is that visitors to my website can addicionar properties. I enabled the option "Allow users to add own objects through frontend on the backend", but do not see any option on my website.

But none of the 4 differents types of item, create item for addiction properties from the frontend.

In backend, go to "Menus", click in your menu.
Add a new item menu.
Select the "Object Administration layout".
