I'd like to have an "Send article" - where just a new email-message pops up and a link to this article is included in the text-field.
This would be much more comfortable than the emailarticle-formular you are providing (although i'll use this functionality too). Nevertheless, i can't find the correct formular to add a new button which provides the functionality mentioned above.

Shouldn't it be added to the article.aspx somewhere????
