Good morning;
I have also received the "Invaldid Social Group" message when trying to read some messages posted. There has been no, I repeat, no response from "the administrator" at this time, about a week following my first problem with this, and the sending of an internal message to "the administrator" using the link provided.
Is it time to go to the more public arena of the "Feedback and Discussion" section of the APUG Forums listing?
Enjoy;
