One thing to look out for is making too many changes at once. You can usually get away with a little bit of refactoring at a time. (Well I was in there to fix this bug, and I had a devil's own time figuring out that the variable $aa was actually the base pay-rate and $aaa was the differential rate, so I made a mass change in addition to fixing the two lines that were broken.) People will be more accepting of several small changes spread out several days, rather than one large one. Over time, you will end up cleaning up a lot of dreck with a lot fewer complaints.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
• Want more info? How to link or How to display code and escape characters are good places to start.
