We only know there is some task for a community if we receive it's e-mail (sometimes ignored) or if we enter on the community's control panel.
Some communities has tasks waiting for months!
Will be nice if we have the total sum of tasks on the task number in the user menu.
At the personal task manager we also see a list of communities and it's number of open tasks, so we don't need to show a mess of tasks.
