When posting code on this blog you need to do two things:
Once you have registered go to the Users page and scroll down to “personal options”. Make sure “Use the visual rich editor when writing” is not checked and uncheck if it is. You will now be able to put html in your post so long as you enclose the code within the following tags.

<pre>
<code>
Insert tags, etc here and they will show up. Outside of the tags they will not.
</code>
</pre>

You can then post your code and it will look like so:

[[code]]czoxMDI6XCINCjxwPmEgcGFyYWdyYXBoPC9wPg0KPHA+YSBwYXJhZ3JhcGggd2l0aCBhIDxhIGhyZWY9XCJ1bmRlcnN0YW5kaW5nbmV3e1smKiZdfW1lZGlhLmNvbS93ZWJwcm8vXCI+bGluazwvYT48L3A+DQpcIjt7WyYqJl19[[/code]]
