I just posted a message with HTML code. It turns out, of course, that since HTML is permitted in posts that if you try to post the text of HTML code the software will instead interpret it as actual HTML instead of text, and no one will see it. So you have to do a few special things. For example, the opening angle bracket must instead be an HTML literal, so instead of "<" you'd write "<", where the "lt" stands for "less-than", since the left angle bracket is actually a less-than sign.
This is a bit cumbersome, but it works fine except for one thing: the software automatically translates literals for some reason when you do a preview, so "<" suddenly becomes "<" in the new message box and will be interpreted as HTML when the message is submitted.
At some point I'll get around to fixing the preview code so this doesn't happen, but I don't think there's big demand for this so I'm not going to make it a high priority, plus I think there may be a couple workarounds. I think there's an HTML element for code, and there's another for preformatted text, so here's trying code:
Fake web address
Here's trying pre:
Fake web address
Okay, now I'll preview, but I'll hit back and then submit to submit instead of submitting the message box with the preview, since the above literals would have been translated.
Well, that's just great, both get interpeted as HTML code!
I'll fix this someday, not soon.
