I have never used the forums - I only opened and used the mail service - and I was NOT informed of impending closure. I only found out when I tried to log on this morning.
Totally gutted and I don't believe they cannot retrieve/reprieve our stuff.
Tried downloading the new service and hoped to migrate old folders but not allowing me - message that my account is now closed. I loved using the email service.
Shame on you, Opera - not a good cause to make for a shiny future...
