   Title:
   Use:  <p> text here (a paragraph) </p>

3. Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
4. Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
5. Read Where should I post X? if you're not absolutely sure you're posting in the right place.
6. Please read these before you post! —
   • How do I compose an effective node title?
   • How do I post a question effectively?
   • Markup in the Monastery
7. 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

8. You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)

   	For:		Use:
   	&		&
   	<		&lt;
   	>		&gt;
   	[		&#91;
