Erstell eine snow.js mit folgenden inhalt:
var no = 25; // number of snowflakes
var speed = 20; // the smaler, the faster snowflakes
var snowflake = "snow.gif"; // picture source

Danach lädst du ins root Verzeichnis das snow.gif hoch und schreibst in den Header deines Board zwischen < body>< /body> folgendes < SCRIPT SRC="snow.js" TYPE="text/javascript"></SCRIPT >
Natürlich musst du die leer stellen die ich hier zum darstellen reingemacht hab in die HTML tags weg machen damits geht ;) das ganze sieht dann so aus wie bei mir z.b. auf der weiterleitungs seit www.fs-board.net/index.htm
