I subscribe to several fora. Many of them now allow direct importing of images into the forum posts via drag and drop into the post directly from the file manager.
AFAICS, this isn't possible on this software, it apparently requires hosting somewhere else, and a link to that host site - a multi-step process that inhibits effortless sharing of images.
For a forum about photography, this is a serious lack and, frankly, a major PITA. We'd see a lot more imagery if it were as easy as on this forum software:
