I don't know enough about it to talk, so please those of you in the know about such things share your expertise. Some of our friends here at SciForum use their real names as usernames. Is that safe? To me it seems to leave a door wide open into their possible email addresses and their LinkedIn accounts, Facebook and Twitter and all that. Am I right? Wouldn't it be advisable to create a username that leaves not a hint as to your real identity? Please explain just what phishing is, and how likely identity theft might be if bad folk knew our real names because we exhibit them on a public forum. Thank you.
