Can I change the custom link to my form?

Can I change the Direct Link of my Form? Currently it shows:

form.jotform.com and my name, which I think not a right way to promote such link.

https://form.jotform.com/rahimbharwani/job-ticket 

Any advice please.

Thanks.

Yes, you may use a custom domain, note that HTTPS is not supported yet, here is a guide with more information about it: https://www.jotform.com/help/144-How-to-use-Custom-Domains-with-Jotform 

You may need to contact your DNS/Hosting provided if you have questions about how to add the CNAME record on your end. 

I hope this helps.
