As a follow up to my previous post on web project management, after trying those tools out for a decent trial period, I still hadn't really been able to find something that was simple enough for my clients to be able to work with reliably, or powerful enough to do exactly what I needed it to do.

Lately, I have been doing a trial run of activecollab, which is derivative of Basecamp. I have been pretty happy with it's simplicity/power balance, and for the most part was pretty impressed with it. Some of the best features that I like about it:

• Mostly Ajax interface is a pleasure to work with.
• Connecting to it via my iPhone automatically uses a very solid and familiar interface that has been optimized heavily for that platform.
•  Open source PHP/MySQL that can be customized as needed

So far, I quite like it. Especially the iPhone interface, which blew me away.
