Topcoin,
Seriously, how hard is it for you to post an actual link? All you have to do is copy and paste the url from the web page like I did just below. See, it's easy and gets folks to the article in one click and circumvents the possibility of one typing the wrong PMID number like you just did in your original post. It takes minimal effort to do this. One sure fire way to annoy me is when someone posts and tells the reader to google something to find the link, or search a certain keyword on PubMed to find the article. Just provide the weblink please!
