This is great, but I'm not sure I'm smart enough to do this. How do I set up an alternate profile under my yahoo! account? Is that the same thing as an alias? And how do I make sure that my alternate profile is the one signed up for the group?

I didn't know how to do it either, but no worries...you can just join the group without an alternate profile. I just make sure to sign my trail name to my posts!

At the top, above the green bar, choose Edit Membership. Then under Yahoo!Profile you can make another one.
