Yay me!!! Electronic Robots Take Xenographic Images En Masse
Well, perhaps that wasn't exactly what I had in mind when I chose my nickname...

Nice try, though.
Well, that's just simply a well-kept secret! 
Moiraine is my friend, she understands that I am doing a highly important field study, y'see, and I am helping her develop a new generation of focus pills.
Ah, getting old, getting old, I meant to talk about "xiem", not "ert"! At least part of you exists in Vietnamese!
When I tried to answer the almighty question of "what does ert" mean, the almighty google along with almighty babylon's free dictionary suggested estrogen replacement threapy... does this mean you are not a he, as is well speculated around??
Hm, that's unusual behaviour. I suggest you ask him some questions about it- if he continues that way, call in the cops and an ambulance, that mirror person might be hiding something!
Wow, BFB, or, these days, APoC got it spot on, the skill and daring there!
Shame on you, KZ, for generalizing. I'm the only one
odd behaving dead cow.
I hope you include Moiraine's name when you publish your so called "scientific" study in the renown scientific Journal of the Telepathy and Psy Academia... if you meet their standards and pass through their demanding referees, of course.

I'm very offending with your suggestion that I'm not a male dead cow! How dare you! Of course I am. How could anyone think otherwise? If you continue that silly line of thought, you might as well claim that it's impossible for me to be a dead cow. Ridiculous!
Now, the estrogen replacement therapy is necessary due to a rare disease that I have. I won't go into detail.
[spoiler=disease?]Of course not![/spoiler]
I just called the cops and an ambulance. They arrested the person on the mirror after I sue him for stalking. The court process took ages and I had to be present, of course. That's the true reason for me to be away from the forums for so long. But I won and that person has now a restraining order. Now, when I look in the mirror there is nobody there. Thankfully!
I just hope KZ returns someday to read my reply.
Whether or not this was already known, Ert has his google in Portuguese!!! A step closer!!!
Ah! I miscalculated move on my side! Nevertheless, it's still possible that I was visiting Portugal for a few days or using a friend's computer.
Erdõs
Richard Feynman
Tesla
Xenocrates
Isaac Newton
Einstein
Maxwell
His favorite mathematicians, physicists, and scientists!
That's actually a very good suggestion! I really enjoy those areas in science and the list is well populated. But, unfortunately, that's not the meaning of my nickname. Perhaps because I didn't thought about it when choosing it. Furthermore, there is the small point to be made that in that list sometimes it's the first name that determines the letter to be used and other times it's the family name. I would never do such a thing!

Richard Feynman's books are amazing (namely,
Surely You're Joking, Mr. Feynman!).
Einstein was amazing, and apparently he was quite a character. Erdős was eccentric, to say the least. Newton, Maxwell and Tesla are classics. Xenocrates is less well known in these areas, but is a good representative of the ancient Greek scientific heritage.
So, keep your suggestions coming. Perhaps somebody will get the right answer.
