Categories are the equivalent of different Forums or Rooms of Matrix. I would suggest the following Categories to begin with:
- Categories for PTA software:
- ledger-cli
- hledger
- beancount
- text editors
- Categories for Double Entry Accouting and Acounting discussion:
- accounting
- General categories:
- Site or Meta (for discourse/forum related topics)
- ¿private category for site admins?
It is also interesting to not have too many categories, just the required ones. Because too may categories make difficult to assign topics to one category. Or then moderators have to move topics from one category to another one.
