Can I use a different display name or profile on different blogs?

A single Blogger account can only have a single profile, so if you have multiple blogs that need different profiles, you may want to put them on different accounts. However, if you just want something to display differently on one blog (that is, you don't need an entire new profile page) then you can modify your template. Just type your desired display name or profile information directly into your template, rather than using the default Blogger tags.
