OK, first of all, you need to calm down, and consider the fact that folks like ww have been here a lot longer than you and probably understand things about how this site works that you have no clue about.

There ARE NO UNCLOSED TAGS IN MY POST

In fact, there are some improperly closed tags in your post, specifically, a few occurrences of the sequence <i><b>...</i></b>. (You've also got a couple other minor HTML infractions, such as not closing your <li> tags and not enclosing your <li> list in <ul> tags.)

Now, you would know this, just as ww knew it, if you had your HTML error reporting levels cranked up in your Display Settings.

i used <pre> tags to preserve the <code> in what appears to be in <code>

If you looked closely*, you'd realize that your post is not the same as BrowserUK's post: you used <pre> tags where he used <c> tags. Yes, <c> tags. Which you would have and should have known about if you had ever actually read Writeup Formatting Tips. This is precisely why the gods invented the <c> tag, and why the admonition against using <pre> tags is not as lightly waived as you'd like to imagine.
