Thinking like a traveler, I attended the CINNUM users group meeting yesterday.  Estimating was the topic; I did pick up a few items.  At the end of the meeting, the group was introduced to Agile Zen. 

Zen is a project management web tool that resembles a cork board I often use for providing insight to all team members on tasks.  Simple site, very clean.  It provides swim lanes where you manage index cards.  Check back later this month for the site to go live.

From my registration, I notice a nice email that was sent by MailChimp.  Another very clean site and a service that I have been looking to include with one of my products.  I will keep you posted on my findings.
