First, why should you care? Because lots of really smart people use Yahoo groups (and ScrumDev in particular).
Second, why should you worry? Because lots of people hear stupid things or get into flame wars on Yahoo groups (and similar). You must Think For Yourself.
1. How to get there.
Go to http://groups.yahoo.com/
In the search box, type in Scrum (one example)
Click on Scrum Development
2. How to join
At the home page, click on Join This Group!
You will be asked to Sign In or Sign Up (become a “member” of Yahoo…it’s free)
3. How to read
From the home page, click on Messages (upper left)
In your Edit Membership (or when you join a group), you can say if you want single or daily emails when posts happen. I like Daily.
4. How to Post
One way: Under Messages, click on Post. That gives you a window to make a post.
Or you can send an email.
Or you can reply to someone’s post.
OK. Now change the mindstream.
