I need help too and I can’t find my problem in the forum because I don’t even know how to write the question down. I need to change the url that shows up under my signature (name) on my blog (article). My domain name is https://www.financialfreedomsunlimited. I want people to see the http address in my article and click on it but I need to change it from https://www.InfinityMarketing2008.com to https://www.Rejection-Free-Internet-Biz.com.

How do I do that?
