SysOp is an Abbreviation of system operator. There is a long standing ReligiousWar over the correct pronounciation of this, Of course, syss op is correct, and sigh sop is wrong. :)

The most common usage of SysOp is as the person who ran a BulletinBoardSystem.

I have never ever heard anyone pronounce this as "sigh sop", and if I did, I would probably have to hurt them on principle. I am not able to rightly comprehend the kind of confusion of ideas that could provoke such a pronunciation. -- JohnMcPherson
