I just migrated my blog over to WordPress from Blogger. I have a custom domain, (www.loveplayandlearn.com) that has been redirected and is working just fine. Everything imported over correctly although I've not been able to find out how to have the old blogspot url (2loveplaylearn.blogspot.com) redirect without the message from Google about redirecting to a non-blogspot site. I have the 301 redirect plugin but that doesn't seem to help. There are other blogs that have been directing traffic to my site using the old URLs and I'm sure that visitors are leery once they see the redirect notice.
