Sorry for the delay on this - I missed the other response.

This could be done in a plugin, you can either write a global interceptor or add a filter. Basically, the idea would be to catch the user if they do not have an extended user property set, and hold them at a page. Once they "accepted" the page, they would then have a user property set that would then allow them to bypass this on subsequent calls.

Marcello,

Take a look here for the plugin documentation:

http://www.jivesoftware.com/builds/docs/clearspace/latest/BuildingPlugins.html

It is possible that someone has created something like this - but it might not meet your exact needs.

You could then extend Filter:

public class TermsAndConditionsFilter implements Filter { }

spring.xml:

    <bean id="termsAndConditionsFilter" class="com.jivesoftware.plugin.termsandconditions.TermsAndConditionsFilter">
        <property name="jiveGlobals" ref="jiveGlobals"/>
    </bean>

Then inside that filter you can do what you need to do in terms of checks - you can always display the splash screen on entry...you can keep track if you've displayed it before, etc.

Cheers,

Anthony
