Adding html links

I want to add HTML links to external websites in some of the fields. I have this working successfully as long as I use some link text to name the link. e.g link text
If I try to enter the link without any link text, i.e. just the URL, Omeka does not read any of it.
Do I have to repeat the URL as the link text in order to display it? Ha! I think I just answered my own question whilst composing this but your input would be welcome!

Yep! Without the link text, there will be nothing for the browser to render as a link. It'll still be there in Omeka, just invisible in the display.
