I've some problem with e-mail notification.
I would like to receive e-mail notifications for each new document or news or messages on forum on projects I'm involved.
I would like to receive too a mail on all messages about issues I'm involved in or I watch.

If I check, on administration settings, all e-mail notification then I receive all issues, even if I'm not involved in.
If I don't check Issues on administration setting, then I don't receive any notification on issues, even if I'm involved in.
If I change, on user preferences, e-mail notification to "Only for things I watch or I'm involved in", I don't receive any notification about new documents, news and forum that are added to project.

Should be nice to add a watchable option (like issues has) in documents, news and forums at high level, so I can check it for project and I can be notified on every change on them.

Thanks a lot, any help will be appreciate.
