Hello @Hhampuz,
I have a question, is it possible to update my initial posts number ?
Indeed, during the week, many of my old posts were deleted / merged, breaking my initial post number
Other participants in the campaign gave you right answers that the manager counts posts eligible based on publishing dates of your posts and your post quality of course. The start postcount of each week in the spreadsheet is only a reference number. You don't have to worry about that.
Anyway, I think it is better if you shoot the manager with PM (as guided in the previous page) with such problem rather than clog the thread. My few cents to contribute.
As always, if there's any questions or concerns, send me a PM and I'll respond asap.
