I think most people here are trying to be anonymous members.
My concern about the anonymity though is that I would like to have some idea of the kind of people I talk to on the forum. I would like be aware of the gender and age at least. Also, I would like to be aware of if they are affiliated with the SSPX, affiliated with a regularized traditional group, sedevacantist, conclavist, etc.
You realize if they could simply lie and say they are regardless of what they really are?
Anyway, the reason is i have made the mistake in the past of sharing information I shouldn't.
Just don't do it without very good reason, and never in a place everyone can see. It's just not worth the possible consequences.
