Nice one schermerberger ... nice sound, good pitch. I especially like the classical piece. Keep 'em comin'.
The url: if you include the http:// bit, you don't need to do anything; it becomes a link automatically as you can see
http://www.soundclick.com/schermerberger . Your mistake was not to include the closing tag, the one with the forward slash (/) in it. You need to click URL to open the tag, then write the link, then click URL again and it will close the tag.
