The process of transforming my "Steaming Pile" blog at http://mnthomp.blogspot.com into "Matt's Maunderings" at www.mnthomp.com is mostly complete. I need to make some changes to the theme / CSS - pull the title a little closer to the top of the page, move stuff around on the side bar - and add some content - the "about me" page, my photos, feeds, resume, etc. - but it's coming along nicely. Steaming Pile still may have been a more appropriate name for what I post here, but it doesn't sound very professional or adult. Although, when you think that I started this whole thing in 2005, it isn't so weird.
***...So, I thought the process of transferring your Blogspot blog to a domain that I bought through Google and have Apps for Your Domain running on would be easy, quick, and simple. I was wrong. Turns out (obviously, in hindsight), that if you have the "Sites" service running on your Apps account, then you can't publish another site on top of it, because sites.mnthomp.com and www.mnthomp.com both point to the same place. Duh.
Luckily, after a bit of digging (not simple) and some poking around with the domain management setting of my domain host (not easy), it all falls into place. As soon as the DNS records update (not quick). These two webpages were invaluable in helping me sort it all out: The Blogger help page "create a subdomain through eNom" (since "www" is actually a subdomain) and the post "Another blog is already hosted at this address" at The Real Blogger Status blog.
This still leaves me with a small question in the back of my mind. My Apps account and my Blogger account are not the same. How did Google let me put a Blogger blog attached to account A on a domain that is attached to account B? I mean, I did have to change some of the domain settings that you shouldn't be able to do without access to both accounts, but they were not major changes. So could I just start entering random domains into the custom hosting box and see of one takes? Not sure how that would turn out, but I'm not gonna find out, either. I'm leaving well enough alone!
