Hello Tom!
I would like to know how to change my username for privacy reasons with regard to people I know, and whether it is possible to delete old messages or restrict access to them, or simply to change the username for those messages, because I discuss very personal matters and I do not want at all for someone I know to recognize me. Some people in my circle know the username I am currently using; I should have thought of that beforehand, but oh well!
Please help me!
