Hi Alec @asmecher,
I and other colleagues of PKP OJS 3.x are long waiting for the release of PKP PN plugin. I would be highly obliged if you or any other team mate of OJS can please update about the estimated date of release of this plugin.
The possible release date of PKP PN plugin will lower the anxiety level and worries of many users of OJS 3.x in their journal management endeavors through OJS. I nonetheless understand the untiring efforts to improve OJS on your part.
Many thanks and regards. Sulaman
