Category Community: This could be focused on Agile Project Management or other specific categories based on client industry. This may be open or closed but is more focused on the content being categorized in a way that makes it easy for learners to find the community and see what relevant training is associated with that category. Ex. Leadership Development community.
Topic Community: This can be leveraged for more open-ended communities. Ex. Well-being community that is open with no required members (only voluntary). Shows ways to maintain physical and mental health to support the workforce in an organization.
Official Community: more targeted to closed communities you want to assign. Ex. Police Department community that has police specific training and employees are required by job assignment.
