Forwarding Blogger Blog to Own Domain Name

[swarheit]

Hey there fellow Bloggers -

I recently started a blog here at Blogspot and I now want to forward the site to the new
domain name I've purchased (link removed) but I have
one question first. A number of my blog postings have made it into
the Google listings, and even though through Blogger I know that all
of the old links will automatically forward over to the new address
seamlessly, I am worried about Google losing my rankings now that the
web address is no longer [link removed] and it now
[link removed].

For those that have forwarded your Blogger blogs to a new domain,
while maintaining to host your blog at Blogger, is this a problem?
Should I worry about the links I currently have in the Google search
engine vanishing if/when I switch over the address, or will they stay
where they are?

Thanks a lot for the help, I really appreciate it.
