I am sorry for not answering earlier, I guess I am somewhat avoidant.
As for your invitation, thanks. Yet I am not really the social forum kind of person, and I rarely join forum groups. And I don't really like the concept of a group based on your name, even though it is just for fun, gives me an impression of 'we and them'.. (no intention to trash-talk your group, I just want to say that it is nothing for me)
