Nasrudin,
I'm not sure if separating the posts themselves to different threads might be the best idea, since in my mind, it sounds like it might only complicate the organization more? The biggest issue I see with splitting them into more threads is that it would encourage more discussion in those threads bumping them to the top instead of the linked threads or new threads making further organization of new information that are good (in those posts) more difficult. I also have some narcissistic liking for the way the thread in the current form flows (in my mind of course) from picking psychiatry to matching in psychiatry. 🙂 However, I'm certainly flexible if the forum consensus is to break them into many smaller threads since it was done for the forum members after all.
Also, it's still possible to link to specific posts within the thread for direct access to the specified topics, although that'd increase the redundancy. I'll separate each topic to a different post now to make that easier.
