Thanks admin, i just had to follow step 6 on that, i gues when i installed it would't creat a new page, it only installed it.
6. If you haven't deleted the default Contact Us page from the Page Editor (CP -> Page Editor -> Pages Management) then it will appear on the menu automatically. Otherwise copy the code of the created E-mail form (e.g. $MFORM_1$), go to Page Editor -> Add new page and paste this code.
