Un-book mark?

How does one un-book mark – I have repair and maintenance bookmarked and would like to quit recieving every comment on that section in my email.
Thanks for your help!

Hi Mary, are you receiving notifications about the gas smell discussion? Go back to the page, and click on the yellow star to the right of “Repair and Maintenance.” It should go back to being an empty star outline. That will turn off the e-mail notifications.

Wow. That is a terrible user interface. There is nothing to indicate the purpose of the star. A mouseover that says “bookmark” is worse than useless.
