oh, I like this!

the mentions constantly annoy me, and everything else (like friend requests and private messages), I get notified about anyway by email, so it's mot like I need an onsite prompt

I guess part of the reason we have onsite notifications is that not everyone chooses to be emailed about these things (which begs the question why we don't get emailed when we're mentioned, hmm.)

but an option for those of us who want too to turn notifications off is a good idea
