Change “My Account” to “Sign in/Sign out” option in header in magento rwd theme?

Question

I want to change "My Account" to "Sign in/Sign out" option in header in the upper right corner.

In C:\wamp\www\magento\app\design\frontend\base\default\layout\customer.xml

I changed

<default>
    <!-- Mage_Customer -->
    <reference name="top.links">
        <action method="addLink" translate="label title" module="customer"><label>My Account</label><url helper="customer/getAccountUrl"/><title>My Account</title><prepare/><urlParams/><position>10</position></action>
    </reference>
</default>

to

<default>
    <!-- Mage_Customer -->
    <reference name="top.links">
        <action method="addLink" translate="label title" module="customer"><label>Sign In/Sign Out</label><url helper="customer/getAccountUrl"/><title>Sign In/Sign Out</title><prepare/><urlParams/><position>10</position></action>
    </reference>
</default>

Still not displaying Sign In/Sign Out....

So how to do?

Answer 1

<default>
<customer_logged_in>
    <!-- Mage_Customer -->
    <reference name="top.links">
        <action method="addLink" translate="label title" module="customer"><label>My Account</label><url helper="customer/getAccountUrl"/><title>My Account</title><prepare/><urlParams/><position>10</position></action>
    </reference>
</customer_logged_in>
<customer_logged_out>
   <!-- Mage_Customer -->
    <reference name="top.links">
        <action method="addLink" translate="label title" module="customer"><label>Sign In/Sign Out</label><url helper="customer/getAccountUrl"/><title>Sign In/Sign Out</title><prepare/><urlParams/><position>10</position></action>
    </reference>
</customer_logged_out>

Try that.. the idea is to put it inside this tag "customer_logged_in" and "customer_logged_out"
