I think I get the Idea of GridField after working on my gallery module, but there is more to learn ;)
I should be able to use DataObject::SomeClass->get()->Filter(array( 'MemberID'=>'CurrentMemberID) ,.... then use renderWith to use a custom template for the new dataList created by that filter ? does this sound correct ?
I see the forum module is updated to SS3 ;) .. do you know of any SS3 compatible UserProfile manager/editor like the one for SS2.4 ? If they are planning to upgrade SilverStripe.org to SS3 I think they will be upgrading the UserForum module soon ?
When I start working on the forum module, I will make sure you get a button to list all Posts by members & a tick box to mark as spam .
Back to messing up with some code :)
Edited :: BTW, doesn't removing the 1st post in the topic remove all sub-posts ?
