Sometimes I leave an URL on my Messenger personal message field,
eg: Berno - http://australianit.news.com.au/articles/0,7204,20721457^15321^^nbv^,00.html
Nasa, a lead from the Messenger team had blogged ("Tip for those curious but lazy! :)") a tip on how to acquire the URL with two single steps!
No more tedious character by character coping the URLs!
