The question, "How to migrate from Blogger to Joomla?", has been done to death. If someone feels the
need to include the URL to a
brand-X website and invite members of the community to "check it out", then this is disingenuous advertising at best or it's just plain forum spam. In either case, there are clear rules about self-promotion and, especially, about posting links to websites that have nothing in common with Joomla.
Further, it is against the forum rules to have a username that is [virtually] "identical" to a website.
I don't understand why we "redact" URL links to non-Joomla websites when people show no respect for the forum rules in the first place (especially when it's someone's first post on the forum). We would send a clear message to first-time posters if we just removed the topic and save everyone's time; however, now that the offending URL has been redacted, the topic could be merged with—and probably forgotten—any of the hundreds of other topics that deal with this "issue".
Lastly (and just because I'm in a generous mood), here's the answer to the OP's question:
