I have a number of email addresses. I use cyber cafes. I use some of my emails to torment my friends without them knowing who I am. The problem is that I open my real email on the same computer. I usually open the real one then I clear history,cookies,temporary files from the comp then I open the fake. Some of my friends are very smart online and I am afraid they will know it is me. Advise me on what to be doing and not doing. Is clearing the history,cookies etc. really necessary. Pliz advise me fully, really fully, pliz.
