Since youre a beginner, i wont mind that.
Its understandable that a logo you create might have been created earlier by someone else.
I had no idea of the earlier EM contests design in my mind and maybe as i had gone through the designs of that contest in the past so the new things that i thought of, turned out similar to previous designs.
But as none of my entry is an earlier WINNING design, its alright to me!
And i hope that people here will learn to use the PRIVATE MESSAGE option :)
