But I found that the forum have send many topics to my email box everyday,and most of these topics are not relative with the questions I want to discuss with the other users,I must spend time on deleting the Email items.Therefore,How can I unsubscribe the topic which is not relative with my questions in order to tell the manager not to send those topic item to my Email box.If anybody can tell me how to solve it.

Thanks you for help.
