FTR: I like "the topic bell,."
Would like to see the tool tip changed for it when it is activated. When activated, it should say something like "You are receiving notifications of new replies in this topic."
However, currrently after it is clicked and I am following the topic, the tool tip still uses the wording for the bell when it is not activated.
And yes, I changed the color of the active bell in CSS to make it stand out. The default dark green was too dark.
