DOGBOY 49
I am really surprised to know that this is your real picture 
its really amazing. And 2nd thing which gave me shock that you started your career in 1971 and I was born in 1986 
and from your career history and your age your name should be Doguncle or at least Dogman 
I was thinking that you are an Indian guy of age between 20 to 30 but its surprising to know that you are near 60 if I am not wrong. You see this is the reason that why I am in favor of using real picture 
Well here in Pakistan we use the same words as you use in your country (Veitnam if I am not wrong) but psycho is the extreme word and we can say crazy managers. I have also not faced any crazy manager like this who don't allow to open SCN at work place and I am not sure why they will stop us by doing this. If they want us to work in SAP environment then how would we do that without SCN support. For me SCN is back bone and if my employer asks me not to open this then I would be looking for some other job or option.
Why you chose this name is an interesting story but do you think this is a valid reason of going with fictitious name on SCN

Ok I agreed your reasons and logics why they have real names in About Scn page. But if you see all members here on SCN as a whole you will again see that majority is with their real names. Ratio of members with real names and fictitious names are different and most of the users go with their real names. Do you have any explanation for that
