So, in cases like this, you want to do a little investigating to see why the problem is occurring. I pulled up MediaWiki:Welcome-message-wall-user (example where the font is correct) and Thread:49555 (example where the font is not working), and looked at the HTML source code for both pages in the Chrome web browser. I took the following screenshots and uploaded them to my test wiki:
 * (screencap) font working properly
 * (screencap) font broken, not working

This investigation reveals that your verbatim'ed &lt;link&gt; tag is not present in the thread page, and this is why the font doesn't work there. As for why the &lt;link&gt; tag isn't there, well, the logical conclusion is that one of two possibilities: I assume you know how to test which one of these two possibilities it is, so if that's something you want to know, I leave it up to you to test it.
 * Verbatim may not work inside message wall/thread posts at all.
 * Or, maybe verbatim works in message wall/thread posts, but the welcome bot itself is designed to ignore verbatim's when it makes its automated posts.

So, that's the what and the why. With this information, can you think of a how to workaround this problem?
