Why no mixed reef discussion forum

[South Carolina reef]

Why isn't there a mixed reef forum under general coral discussion?

A mixed reef consists of a bunch of different life and is a type of aquarium. Its simply labeled as a reef aquarium on the forum topics. You dont generally label the type of aquarium by the type of coral. It would just be either called a (insert coral type) dedicated or (insert coral type) dominant reef.
This is of course my interpretation over my decade of reef keeping.

The reef aquarium forum can be found here.
