Final update on this topic - Wahoo! It worked, it actually worked... There are some hoops you have to jump through to get your blogger site to point to your godaddy domain, but once it kicks in, it works just fine. Or at least so far. :-)
UPDATE (4/28/09) - Okay, my idea did NOT work, and it turns out I am going the hard way about things. If you want a custom domain for your blog, do what Patricia did at dingedCorners: use the blogger settings and let Google handle everything.
I opted, some time ago, to use GoDaddy. I have found a step-by-step that should get things going, but I won't know for a day or two. Looking back, I wish I had realized I could have done the whole thing through Google instead... Ah well, live and learn.
Just a quick word... tribecards.net will disappear for a bit. You can still get to tribecards.blogspot.com but the .net might drop off here soon as I figure out this whole hosting thing...
Thanks for your patience... If you've made it this far, you already have more patience than I do. :-)
