en.wikipedia.org/wiki/The_Signpost

The infobox describes The Signpost as a "Monthly newspaper," but the publication's own official "About" page says it is "currently published twice a month."

A second official Signpost page, its content-guidance page for contributors, also describes a schedule tied to the first and third Sunday of each month, which likewise indicates roughly twice-monthly publication rather than monthly.

Because these are official Signpost-maintained pages describing the publication's current schedule, they directly contradict the claim that its type is "Monthly newspaper."

This sentence says The Signpost "is now published monthly," but the publication's own current documentation says otherwise.

On the official About The Signpost page, The Signpost says it is "currently published twice a month." Its contributor guidance also gives the routine publication cadence as the first and third Sunday of each month, which is a twice-monthly schedule.

So while the publication may at one point have moved to monthly release, that is no longer its stated current frequency. The sentence is therefore outdated and factually incorrect as written.
