I find message notifications that were introduced recently most usefull in many situations. But I'd like to suggest some improvements:

* Bug notifications - I don't need to be notified of my own posts in bugs. I mean, I know I posted there :)
* Board replies - I'd like a new "sub-option" when activating these notifications to activate them only for boards that are not my favourite boards. I read my favourite boards every time I see a red number indicating a new post. I need to be notified of replies to my messages on other boards, that I visit less often.
* Board replies 2 - same thing as with bugs. If I reply to my own message (sometimes I do that, to keep the message in the same thread) there's also no point in sending me a notification about my own posts.

While I'm at it, I think it would be interesting to add another option for bug notifications - the hability to subscribe to a bug. This way people could be notified about the bug's progress without having to post there. Let's suppose my opponent finds a bug in our game and posts a bug and then informs me about it. I could just subscribe to it and be automatically notified about its progress... especially since I may be an important part into clarifying some aspects of the game as well...
