Why does this page exist!?

A light-hearted way to indicate the correct spelling of 'SystmOne'.

"In the world of Peter Pan, if a child says they don't believe in fairies a fairy falls down dead; similarly, every time a SystmOne user misspells SystmOne, I die a little inside." - Alexander Ratcliffe

What about shorthand like "S1" and "SOne"?

As long as it's already in context that can make sense. If not, it would seem sensible to first use "SystmOne (S1)" in a document to create that context.
