You can share this webxdc app e.g. in a Delta Chat group.
Every group member can read and change this memo.
Use it e.g. to keep all relevant dates in one place if you plan a meeting with your friends ;-)
Or simply share this App into your "saved messages" chat. You can add a shortcut to your homesreen and you have your memos on all devices where you run Delta Chat. For better overview if you use more then one instance, you can set a title for every instance since version 1.4. This title will also used for the name of the homescreen shortcuts.
You have just to run "create-xdc.sh"
The created "Memo.xdc" now can just sent in your Delta Chat group or also in every single Chat.
Every user have to use a Delta Chat App. Webxdc Apps works not with regular Mailclients
