Amelia L.'s dashboard

I've just signed up for No Kahuna because of a) its affordability and b) it's similarities to Basecamp with regards to usability.

I see there is not a way to set milestones and I read that people use Categories to accomplish this. However, without a calendar to warn you of impending deadlines I'm confused as to how everyone is using this.

Anyone have any suggestions or can you tell me how you personally set Milestones?

Many thanks!
