If you want to be even more anonymous you can change your username to something even less related to you. My user name is extremely general and tells you absolutely nothing about me. Also, if you google this username you dont find me. My location is likewise very vague, although it tells you that i am in England and roughly which area, but no more.
If you are posting in this section of the forum anyone can see your post, but there are sections of the forum where your posts can only be seen by other members. If you want to post something a bit more personal, its probably best to post there. I never post things that can identify me, although I have met some of the members in real life and they know Im not really a 30 yr old male truck driver!!!
