nedd3h: if you know exactly what lines need to be changed in a .script file, you can always go ahead yourself rather than wait for it to go through the full community process.
Backup your fritzbot\Fritz0.pk3
Associate .script with notepad.
Open the .script file with inside the .pk3 (path is \maps\). BTW use Winrar not Winzip (see below)
Search for the line to be changed. After making the corrections, save and close. Winrar will detect that the copy in the temporary directory was changed and ask if you want to update (say yes).
Don't use Winzip because it may save the new version in the root rather than \maps\.
And that is all there is to editting .script files.
NOW HAVING TOLD YOU ALL THAT...
I much prefer the alternate solution of adding the caen2_soundfix.pk3 file to etmain. That way the fix works for all variations of ET not just Fritzbot. Also logically the sounds should be prefixed caen2 not caen which the soundfix supports but the script edit method does not. (the client download issue is trivial since the pk3'd .sound file is smaller than the .script)
(p.s. The clipping exploit fix you mentionned I did not see but the banimod thread you referenced is 5 very long pages, and I do not have time right now to read through all of it.)
