4.3 Advertising and links in signatures
Links to one's own, private or business websites are expressly permitted in the signatures, provided that they do not involve Internet content that is in direct competition with the content of the Zetorworld.com pages. Links to your own, commercial homepage are permitted in normal font size, thickness and color, but NO references to ongoing campaigns, no offers, requests to buy or the like. In case of doubt, the final decision as to whether a link is permissible or not rests with the administration.
