I'm assuming he means yours. Shortbreak's and neoeon are just ascii-to-hex. To translate:
Shortbreak:
Speak Hex, like the rest of us. ;)
Neoeon's reply:
I like talking in hex too ;-)
But I wonder what this cipher above means - the sequence 123 is repeating too often for my taste!
Shortbreak's reply to that:
I am suspicious of 1234543210 at the start of the 4th line.
As for me: I'm convinced that your message is a substitution cipher that uses certain number patterns for letters. But I have no idea :P
