I question this statement.

Series En Fuego to me always meant series that were very popular and garnered a lot of replies. Often they will also be subbed by a speedsubbing group and an "archive" group weeks later, thus creating a need for threads were viewers of only the archival quality would not be spoiled and could remain relevant. These are series that would otherwise get their own subforum, but are not ongoing long series or are frequent recurring series (like Gundam).

The first step is absolutely that they will gather a large enough following or at least a vocal enough discussion. Series like School Days would have ended up in the subforum.
