Suggestion - Instead of the bell at the top of the page being for total notifications let it be for tags/quotes/upvotes only. We get a notification for Pm's and we get one for subs, no need to have the total be the bell plus the rest. I dunno, just something about having it be a total plus things not covered under Pm's and Subs seems a little disorganized. 

So say, we have 3 Pm's, 4 Subscribed topics posted in, and 1 tag - instead of the bell reading 8 total, it would just read 1. If that makes sense.
