Hello everyone, I truelly and honestly respect and honor your help, and you
have provided me with very (I mean very) interesting ideas. I will discuss
them with my instructor, and if he said "it is not challenging at all"

Again, every one thank you soo much. I will tell you on which topic we will
settle soon.

Have a nice time and good luck with your studies.
