global logout link (find out csrfKey)

[Omri Amos]

Hi,

I need to have a link that will allow users to logout.
If I use simply "domain.com/forums/logout/" it does not work at all because of the missing csrfKey, and shows me an ugly error message:

The CSRF protection key did not match. This may indicate a plugin or theme is out of date. Please contact technical support for more information.

Error code: 2S119/1

Expected behavior was to show a confirmation message to the user....
Anyhow, how can I get the user's csrfKey in order to make a generic logout button for him?

thanks

Example:

<a href='{url="app=core&module=system&controller=login&do=logout" csrf="true" seoTemplate="logout"}'>{lang="sign_out"}</a>
