The Log In Message pluging doesn't seem to like HTML hrefs

The Log In Message pluging doesn’t seem to like HTML hrefs embedded – the display just cuts off, when you actually look at the page. I haven’t tried any other tags.

For example, I used a version such as this:

Welcome to xx. This site is not open. Please a href=”http://xxx.org” to go to our public site.

(I am removing the brackets for the purposes of this example.

But the display on the actual login page stopped after the word Please.
