What does OP mean?

[Skyline]

The title says it. When going through forums when a mod/ admin posts: OP request, or OP... what does the OP stand for?

[StoppingTime]

OP means "Original Poster" as in the user who started the thread.

[Rayquaza]

It can also mean "Original Post", as well as what Steven said too.

But back to the OP,
