Random thought.
Rather than a separate forum for Epiphyllims, perhaps the title of the Cactus and Tender Succulent Forum could be amended to include Epis. People who like to grow Cactus and Tender Succulents might also be the kind of folks who like to grow the Epis. (?)
Cactus, Orchid Cactus and Tender Succulents or
Cactus, Epiphyllums and Tender Succulents.
