rules prohibit posting of affiliate links ,as was stated above
but if you really really want to promote,you have several  options that don't break the forum rules:
a)use your signature
b)create a site or a blog ,post your reflinks there,create ANN thread in the service section of the forum to promote that site
c)according to Lutpin,there is an exception for so-called "tipsters" in the gambling section,so if you are one of them-use it
