Hello MT,
I've put a lot of thought into this Anonymity thing.
We need the safety to make sure our information does not leak to the outside world. That's why at meetings, and on a public forum, we shouldn't post our full names, addresses, phone numbers, and bank account numbers.
However, as we get to know each other in-person, as we know who is safe and who can be trusted, we can share our personal information. I have hosted GYE get-togethers in my house, and know many people's first and last names, phone numbers and addresses, and I even know some bank information for some friends in recovery, too.
Our problem is living a double life. Having a fake name doesn't help us get better in that respect. As long is your name is fairly generic "Avraham G," no matter what you post here (outside of your last name, address, and phone number), nobody is really going to ever figure out who you are (though everyone thinks they will be found out). OH NO! I WROTE THAT I LIVE IN A FRUM COMMUNITY! FOR SURE EVERYONE KNOWS WHO I AM NOW!!!
Furthermore, I have seen people on this forum, and quite a few of them, start to have issues with other people on this forum--much like in real-life relationships. The cure? Log-on with a new name. I have sometimes had the pleasant experience of being the minority opinion in a debate here only to find out that all the people I am debating against are all the same person! That made me feel deceived and taken advantage of, when here I am trying to offer some help. This forum, then, can become just another game.
In real life you can't just change your name and your face and solve all your problems. Either you escape, or you have to learn to deal with life.
So, using a real name on this forum, I think, helps a person feel more honest, and more of an obligation to be honest, about what they write here. Also, keeping one user name and sticking to it, as virtual as this forum is, I think helps a person start to build up healthy relationships on some level.
Another thing, I have found, is that it's okay to be yourself. Nobody REALLY cares. You're not going to die just because you wrote "Avraham," or whatever your name really is. And, for me, that has been very liberating.
Just my two cents worth.
