Allow Dot us domains in profile

As things stand now, only.com addresses are permitted on the profile page. Support recommended I use a bit.ly link that redirects to my website. 

How difficult is it to accommodate different web domains?

I happen to have a.com that I don't use that redirects to the .us address but it's not my brand. It's not what I promote.

Please make the change to accommodate other domains.

Thanks
