I have been in SL for over one year now and each time I try and get onto the SL website or even marketplace I get this odd message on my screen. ( error (HTTP 500 Internal Server Error) Now I have decided to end my time in SL but I cant even cancel my account as have never been able to log on . Acually being in SL has been no problem its just been acess to the website. Even to write this message I am on my other avatar. Any ideas would be great. Thanks
