Notification Settings & Preferences

It would be great for user experience if we could configure the notifications for changes to projects. Either at a project level, team member level or for individual users. A great example of this is when reviewing the sitemap - if I as the project manager make changes with the client to pages (put on hold) i don't want an email issued to every single member or even myself when the change is made. Having the option to configure this to a weekly roundup of changes / updates to projects that i'm subcribed to / a member of or manage would be far more user friendly. Being able to pre-set the notifications users I invite to a board would also be great, as there may be fluid changes occuring that don't require frequent email alerts.
