I want to cancel it?

Question

I was not necessary

Answer 1

What do you want to cancel?

Do you want to cancel your membership in a Yahoo Group?  If so, log in to the Yahoo Groups web site.  Then go to the home page of the Group you want to cancel your membership in.  Then click the Edit Membership link near the middle of the top line (just below the ad if there is one).  Then click the Leave Group button down in the lower-right-hand corner of the page.  Then follow the directions on the resulting page.

Do you want to cancel your membership in Yahoo Answers?  Because there's no real way to do that.  If so, the best suggestion is to just stop coming to the Yahoo Answers web site.
