MattisManzel:
The mother page of a day-page set has “Pages” in the end of the CamelCase title (or - like in French - in the beginning of it: PagesBavardage?. Both variations can be searched for, see DayPageSandWiki:DayPageSets).
When I made the sand-diki last year that hadn’t been clear to me yet. FirstDikiPage consequently now turned FirstDikiPagePages in CamelCase. It is first diki-page in clean linked spelling.
