I started a thread for kommunity members to post pics of themselves as babies. Turns out I am the only one who can post an image int he thread. After the initial post, the only option is to post a text comment. I think this is a big issue, since it severely limits how members can interact in the forum...which is the main purpose of using Flux. With most forums, you have this heirarchy:
CATEGORY
Thread Title & Initial Post

Flux seems to be working more like YouTube in that the Initial post is the only portion of the thread intended to have any rich text formatting or media or links and everything after that is a comment on the first post. That's not conducive to vibrant discussion. Good boards give you a "rtf" reply box for every post.
I'm hoping this is something the folks at Flux can work out for us. I can give you some examples to look at, if you like.
