If you are serious about writing and keeping a personal journal, never ever use your real name to register. I wish I have known this three years ago. So, now, though I love this blog very much as it is my first blog, I still can never write truthfully. The name is there, people will find out.
I do not mind a thousand strangers visiting it but I freaked out at the thought of someone who isn't suppose to read, discover it.
So, remember, if you are going to start an online journal, never ever use your real name.
