Add some features to a ms access database

I have a small company, and I use ms access for task management. I use the task template from "featured templates." It is good but is missing some essential features which I want: 1. I want to have pop-up reminders when tasks are due/overdue. 2. I created a field called "updates" were we post updates for the tasks. I would like it to be like a forum, where every time you type something in it should automatically display the date it was put in. 3. It should display and schedule the tasks in a calendar view like in outlook.
