Starting a second blog

How about adding an add on domain with your webhost?

you can frequently run multiple domains off of one host….look into that..

You may have the possibility of a subdomain which looks like:
https://newblog.domain.com

Or a subdirectory like this:
https://domain.com/newblog

or even a totally new domain:
https://newDomain.com

so look into one of those options with your provider…..
