@julian Hi, yes for sure. "Source" or "Location" are pretty common data points that add more granularity in organization/sorting/searching. An example of a non text field would be something like "beginning date" and "end date" that would need to be date or number. I'm admittedly new to nodebb, but I it would seem copy/pasting whatever was done to the users codebase and replacing the variables names would be perfect for both categories and topics.
