Henry's recent note reminds me of his earlier note about the wiki concept and so I'd like to point out that WebElements now has a (largely unpopulated) "wiki" at http://www.webelements.com/wiki/ ChemWiki: Chemistry web pages in continual change as a result of efforts by the users. Eventually (hopefully) you will find pages about many aspects of chemistry here - and if you like you can edit them, and add new pages as well. That's the idea in fact. While WebElements is a periodic table thing, I've put a framework in to try and encourage the build up of any chemistry themes. Editing is easy and uses a highly simplified system for adding headings, bold/italics, etc. I do ask that anyone interested might like to try it out by adding a few snippets of information perhaps. It will be interesting to see how chemists react to a wiki. Slowly with a high activation energy I suspect. The site has been live for nearly a month and the stats show many have browsed around it - but that users seem shy about actually adding information. Henry also encouraged chemists to consider providing news feeds a while ago. In that spirit news junkies can see which chemwiki pages are updated via the feed at http://www.webelements.com/wiki/index.php?action=rss Other feeds for the WebElements "blog" and the WebElements forum are at http://www.webelements.com/news/xml-rss.php and http://www.webelements.com/forums/rss.php Please do offer feedback!
