Please do not add inappropriate external links to Wikipedia, as you did to Enthalpy. 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. -- Ed (Edgar181) 13:19, 6 September 2012 (UTC)Reply

Please stop your disruptive editing. If you continue to vandalize Wikipedia, as you did at Organic compound, you may be blocked from editing. -- Ed (Edgar181) 13:22, 6 September 2012 (UTC)Reply

You have been blocked temporarily from editing for adding spam links. Persistent spammers will have their websites blacklisted from Wikipedia and potentially penalized by search engines. Once the block has expired, you are welcome to make useful contributions. If you think there are good reasons why you should be unblocked, you may appeal this block by adding below this notice the text {{unblock|reason=Your reason here ~~~~}}, but you should read the guide to appealing blocks first.
