Help requested on how to create a login and a logout on a wordpress page

I requested help on how to create a login and a logout on a wordpress page. A suggestion was to use theme my login and it didn't work or possibly use a log in on a slider. I am using the Mantra theme. The theme my login in did not appear to have a option for a particular page. It defaults right to my main site for a login. I have an Event plugin and I want a login for users that wish to place an Event and then be able to logout.

I would appreciate some help in how to achieve this with some steps.

Thank you.
Doug
