Long URL distorts the forum layout. It is preferable to put the URL inside some text. Following code will do just that:
SOME TEXT
Replace LINK URL with the actual URL (eg,
http://www.whatever.com) and
Replace SOME TEXT with something like Click here for the link or Link or Cricinfo or Daily Star etc as appropriate.
The same code can be used by clicking on the Link icon, typing some text in the first dialogue box and finally typing the actual URL in the second dialogue box. Remember, First Text, Second URL.
