Hi disc,
I’m the creator/administrator of the website mentioned. I definitely need to take the pawpaw game up a notch. Fortunately someone has offered some information on pawpaws.
As for mulberries/jujubies, I was considering adding a miscelaneous or exotic category to hold more uncommon things. I’ve been approached about things like kumquats, medlars, quince, currants, etc. Dates and Jujubees could go into that category as well.
In the “Support and Feature Requests” section, there’s a spot to request the addition of cultivars not on the list, request additional features, report bugs, etc.
At some point I need to add a tutorial in a prominent spot because I get questions about basic functionality from time to time.
