These links should work on Open Mic's.  Some get tagged as
spam in comments.

Block elements

P paragraphs

The paragraph element requires a start tag, but the end
tag can always be omitted. Use the ALIGN attribute to set the
text alignment within a paragraph, e.g. <P ALIGN=RIGHT>

UL unordered lists

These require start and end tags, and contain one or more
LI elements representing individual list items.

OL ordered (i.e. numbered)
lists

These require start and end tags, and contain one or more
LI elements representing individual list items.

DL definition lists

These require start and end tags and contain DT
elements that give the terms, and DD elements that give
corresponding definitions.

PRE preformatted text

Requires start and end tags. These elements are rendered
with a monospaced font and preserve layout defined by whitespace and line
break characters.

DIV document divisions

Requires start and end tags. It is used with the
ALIGN attribute to set the text alignment of the block elements it
contains. ALIGN can be one of LEFT, CENTER
or RIGHT.

CENTER text alignment

Requires start and end tags. It is used to center text
lines enclosed by the CENTER element. See DIV for
a more general solution.

BLOCKQUOTE quoted passage

Requires start and end tags. It is used to enclose
extended quotations and is typically rendered with indented margins.

FORM fill-out forms

Requires start and end tags. This element is used to
define a fill-out form for processing by HTTP servers. The attributes are
ACTION, METHOD and ENCTYPE. Form
elements can't be nested.

ISINDEX primitive HTML
forms

Not a container, so the end tag is forbidden. This
predates FORM and is used for simple kinds of forms which have
a single text input field, implied by this element. A single ISINDEX
can appear in the document head or body.

HR horizontal
rules

Not a container, so the end tag is forbidden. attributes
are ALIGN, NOSHADE, SIZE and
WIDTH.

TABLE can be nested

Requires start and end tags. Each table starts with an
optional CAPTION followed by one or more TR
elements defining table rows. Each row has one or more cells defined by
TH or TD elements. attributes for TABLE
elements are WIDTH, BORDER, CELLSPACING
and CELLPADDING.

I can use most of the Block elements in comments if they are in their
simplest form.

Text level elements

These don't cause paragraph breaks. Text level elements that define character
styles can generally be nested. They can contain other text level elements but
not block level elements.

• Font style elements
• Phrase elements
• Form Fields
• The A (anchor) element
• IMG - inline images
• FONT elements
• BASEFONT elements
• BR - line breaks
• MAP - client-side image maps

I believe all of these text level elements are also usable on this blog. 
I have not attempted Phrase or forms.

Always end your Open Mic with <!--break-->. 

Delete all of the extra carriage returns you can.  Once
it's good just run all of the code together.  This blog will add a carriage
return for every new line.  Use <br> for line breaks where you need them
instead.

Be very careful.  Test your code in blogger first.  If
it works there, it should work here with minimum modification if any.  Try
a couple of popular browsers.  Commands sometimes work different depending
on which one you use.
