Bignate603, you probably mean the one on a Team AnandTech page - that's not where you join up - the link provided by Yo_Ma-Ma is the right one.
So if you haven't already made a Seti@Home account that's the first thing you do. Then you go to that link and if you don't have the password yet just
go here put in the address you used for your seti account and get your password emailed to you.
If for some reason you don't get the password, reply here again and we can help with that as well.
Welcome to the TeAm!!!
