Linking to Sources When You Post

Many here do add court case citations, regulations, etc., when they write a post.  However, often they do not add the link to the source.  It is very easy.  For example:  U. S. Constitution.  To link to a page with that document go to the source and copy the url.  Highlight the text you want to link--in this case U. S. Constitution--and then click the little "chain link" symbol between the U and the " mark.  Drop your url into the url box and voila--you have a nice clean post.  After you submit your post, the link will become active.
