Laddawn.com : QA task test

Would using this feature be of any value? For instance, if I log an issue, instead of just putting Cathy's name in the "assigned to" box, I put her name in using Confluence task list feature; likewise, if a developer says something is ready to test, they put the reporter's name in the assigned to box, using the task list feagure - whenever this is done  I think this generates an email to the user. I don't know if an email gets generated if the person assigned the task checks the box. I don;t think this feature is very "intelligent" - for insteance, anyone can check these boxes, not just the person who is assigned the task.
