besides the need help? link that dws recommended I suggest you check out the Perl monks site FAQ and site how to guide. The answers to your questions are there.

Just in case the information is missing or hard to get to.

How do you strikeout text?
Use the tag <strike>
How do you underline text? Just kidding.
Use the tag <u>
How do you insert literal [ brackets in ordinary text?
Use &#91; and &#93;
How do you indent a set of lines, or one line?
I use blockquote. Though there was some recent dialogue on the CB about this - you should be safe if what you are indenting is text, not code. To indent code, use leading spaces in the code.
How do you insert em or en spaces in a line?
&nbsp; works

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
