Clicking on your link doesn't work, because it incorporated the comma. Don't know if that is your fault, or the interface, since this is my first post. Here, I will try inserting your link: with a comma https://steemit.com/@easteagle13, and without: https://steemit.com/@easteagle13

Interestingly, only the one with the comma was made automatically into a hyperlink.

What if I try inserting the link with no punctuation, and make it the only link in the post?

Ah, that worked.

Thanks for the heads-up. Much appreciated.
