This is a public forum that thousands of people read. The likelihood of anyone knowing who you are is slim. Why not create yourself here with even less of a chance of someone knowing who you are?
Some people use the name they use everywhere on the internet when creating a profile for this forum. That can seem like a really good idea at the time, but when they start talking about sensitive issues and want to be anonymous, they sometimes find that they are not so anonymous because they have used their on line name.
I suggest that you pick a name that will not indicate who you are to anyone. That way you have the freedom to be as open and honest when you write as possible.
