welcome to GLOBO! Great to have an OZ expert amongs us.
To 1: just get rid of that URL /URL thing take care that no other sign is infront and after the url and it should be done automaticly (example: www.globosapiens.net )
To 2: Login, go to your message, edit button, check delete, ok
Thats it.. pretty easy isn't it ;-)
Cu later,
Andy
