However, the problem arises when it becomes redundant.
We could have different threads for specific tastes, but how long before those threads become forgotten (like what happened with the last PregChan)?
While we could do that, I advocate posting those sub-categories into a single related thread.
For instance, this thread, the avian oviposition thread, and the pregfur birth thread can all be posted under the Pregfur thread. Aby posts the users don't like can be hidden by clicking the "Hide" button next to the file.
