At the moment we have set up to turn the links off for Studio my using a system property, we don't really like this very much but it was the only way while we waited for SAL 2.6.x  Now we have SAL and so can change it to using an application property.

To use the application property you (Studio) will need to add a bit of xml to jpm.xml
        <property>
            <key>jira.show.contact.administrators.form</key>
            <default-value>false</default-value>
            <type>boolean</type>
            <user-editable>true</user-editable>
        </property>

We are happy to go with which ever mechanism is easier/preferred by you guys.
