After you select the items for the week's Harvest list you have the option to Publish or not. Publishing means your members will be able to see the box contents scheduled to be delivered per box. This may or may not be helpful for Fixed Selection type shares; members often want to see the box contents (so they can plan shopping) but IF your harvest is varied and unpredictable then do not Publish. And members will get what they get. This is a week-to-week decision, so not publishing one week will not impact future decisions.
ALL CUSTOM SHARES MUST BE PUBLISHED because the member needs the week's list to customize their boxes!
If you decide to publish, from their dashboard the member will see this:
Fixed Selection share type
Custom Box share type
