Having used Basecamp for project managing client projects for a couple of years now I’ve decided to recommend it via their affiliate program;

Basecamp sux. Enough said.
Everyones entitled to their opinion, I have a simple set of requirements, milestones and to-do lists with access for clients. Basecamp does this.
I’ve also used TasksPro, which is great for task management but doesn’t have milestones.
Well, Basecamp is a good system for those guys who need to chat a lot. It’s a communication tool. That’s about it. I was not enough of a tool for me, so I switched to Wrike, which has Gantt charts and is integrated with email. I’m pretty happy with it.
