I am just wondering how long it takes to have my forums upgraded after I paid for my delphiplus subscription? It says to log out and log back in, which I have done several times, but I still see no chat, and I don't have access to many of the controls. I keep getting an ad telling me to upgrade first, but obviously I have already paid to do that...

Your account features update after a log out - your forum ones will in the morning when the server reboots or whatever crazy magic happens :)
