I hope they don't erase it. In 2006 and 2007 I added IHD on wikipedia under dialysis, renal failure and nephrology, but each time they called it spam and removed it while chastising me for posting it. I argued that it was a help forum for patients, with support and info unavailable anywhere else, but they weren't interested.
Here's the message they sent me:
Please do not add inappropriate external links to Wikipedia. Wikipedia is not a mere directory 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 exist to attract visitors to a web site or promote a product. See the external links guideline and spam policies for further explanations of links that are considered appropriate. If you feel the link should be added to the article, then please discuss it on the article's talk page rather than re-adding it. See the welcome page to learn more about Wikipedia. Thank you.
