My intuition is that the three accounts:
Thyaga
Caelan
Triswardhani
... are the same person. But you do as you want 'engineer123'.
Sorry... from what I read, u say that I'm the same person with those people, which I never notice about the name when I post.
maybe you could check again your intuition.
and by the way, is it allowed to have more then 1 account on BTT?
