Just send your perl script, c source (!) & compiling options (if you want any special) or any other script that runs on linux to my email matrix_man@gmx.net with subject challenge name and your tbs username.
And please be patient, i cannot always check your solution within one day, so just wait, i'll reply to every submission as soon as i can.
One final note:
The folders and executables are exactly the same on my box as on the test-env chrisi had provided.
So all programs are in /home/levels/
Good luck!
