Types of learning community

Content

Hi all,

I'm hoping for some clarity about how others use learning communities and the different types available. When we create a learning community we can see three different types - Category Community, Topic Community and Official Community.

Can anyone help me understand what you'd use each of these for? The 20C notes suggest category communities will be helpful when learners browse the catalog by grouping learning together in a logical way but I can't seem to find anything that references the other two.

Thanks all,
Alice
