Lionheart, your post made me smile, sadly...
I too have done all the things you mention, and still, in various contexts, battle against those silly paranoid fears that lead me to do all sorts of things - post something and then log out and fear coming back, send an e-mail and then battle to open its reply, sometimes for hours or even days, reread something I have written over and over again in ever increasing fear of unnamed yet horrible consequences...
And I'm not only talking about this forum.
I'm much, much better with the forum than I was in the beginning, desensitised to some extent by the lack of negative backlash that has ever resulted from anything I've written here.
Still, cynical and mistrusting by nature, and also far too exposed, through my work, to the dangers that lurk on the Internet and in any place of public information sharing, I believe that others have given good advice about refraining from using identifying information wherever possible. And this isn't about being ashamed of our experiences or of who we are - it's not about denying what's happened to us or feeling as though we don't have the right to stand by our story or to tell it publically, it's just about simple safety and caution which applies to sharing identifying information on the Internet in any context whatsoever. They don't call it a world wide web for nothing, and unless absolutely necessary, my advice would be to refrain from posting personal or identifying information on the Net at all.
Safe is, as they say, so much better than sorry.
