What topics ought to I bring up in my community?

Hello there,
That fluctuates. For every product you recommend, you can write a commentary. If you have a single core product, like news, you can have a subject for each primary action or feature area. For every kind of user you have, including end users, API developers, and WhatsApp developers, you can add a subject or subjects.
Open General Discussion threads for users to discuss topics that don't quite fit into the other categories. You can monitor this subject in case any new issues surface that necessitate further debate.
