Please do not add inappropriate external links to Wikipedia. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site or promote a product. See the external links guideline and spam guideline for further explanations. Because Wikipedia uses the nofollow attribute value, its external links are disregarded by most search engines. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. Materialscientist (talk) 03:00, 30 April 2010 (UTC)

This is the final warning you will receive regarding your disruptive edits. The next time you insert a spam link, you may be blocked from editing without further notice. Persistent spammers may have their websites blacklisted preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines.

You have been blocked indefinitely from editing because your account is being used only for spamming or advertising. If you would like to be unblocked, you may appeal this block by adding the text below, but you should read our guide to appealing blocks first. Materialscientist (talk) 06:50, 30 April 2010 (UTC)
