The issue of editing root nodes is considered a feature, and
not a bug. I don't totally agree with the policy, but I do
understand the reasons for it. Changing a top-level
node can cause havoc (or at least some extreme
out-of-context replies). Hence, the mighty "Preview" tag.
Some top-level nodes *can* be edited (e.g. snippets)
but in general, you just have to be
really careful. Extreme errors can be changed by making a
petition to the gods. For minor ones,
replying to yourself is sometimes the best way to go.
Don't worry about making a post you later regretted
or really, really wanted to edit - we've all done the
same. Consider it a rite of passage. :)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
