Don_Coyote - please read Voting/Experience System with special attention to a couple notions:

1. The existance of a single - - or even a few downvotes of a node is likely NOT significant; consider a single downvote a random event sparked by excess relative velocity in a poly-saturated atmosphere. In other words, don't sweat the small stuff.
2. The "Reputation" of a node reflect the judgement of those who have read it and bothered to vote on it, either because they consider it (well written|interesting|useful|insightful|other_desiderata) or because it (reflects lack of effort - including failure to search standard resources here, www-wide and on dead-trees|contains an ad hominem attack or a slur|complains about others' reactions to an earlier node by the same writer|includes other_utterances_contrary_to_the_local_mores)
3. A node's reputation is NOT the same as XP, nor is it a final judgement on the merits of your continued use of space in which to stand or sit, O², H₂O and nutrition.

Your latest post (the one where you got yourself signed in) comes close to downvote territory on several counts, but avoids one because of the funny observation about deleting your own cookies (except, of course, <Begin nitpick> the cookies set by PM are not yours, but the site's</nitpick>). But for the sake of your reputation and your customers' satisfaction, I do hope you'll postpone the urge to "wite (sic) websites with differing functionalities" until you lock onto a few more of the basics. (That last sentence, BTW, is entirely sincere and not intended as a "slur" but may be read as such... in which case, the saying "easy come; easy go" can and does apply to XP

And further re your latest, DO NOT USE <PRE> TAGS HERE!. Another assignment, this one on another set of PM basics: read Writeup Formatting Tips , Markup in the Monastery and Perl Monks Approved HTML tags.
