cannot help you with that problem but for years i would get e-mail notifications when anyone responded to a thread that i posted or replied on rcu. but that all stopped also. it also happened to a lot of others also. it was blamed on my isp but they were not the problem. someone told me that rcu changed their utilties format or something like that and thats when it started. i have tried for 2.5 years to get my notifications restored but to no avail. i'm probably wrong but i believe the rcu system is just overloaded. one of my flying buddies made a few attempts to get a avatar on rcu also but just gave up.
