One of the search engine submission newsletters I'm buried in suggested putting <!--- description of site -- > between the Head and Title tags. Is there any valid html rules to this, is the space necessary at the end? It was suggested this would help with excite, but that a special page be made for the purpose. I'm wondering if it would cause trouble if added to the general headers, would other search engines view it as hidden text and ban my site? A: Helps, B: Hurts, C: Does nothing. Thanks.
