We want to create a "Success Stories" sub forum. So users can post about stories. The OP would select a prefix called "Story Details" to start off the thread. Other users can comment along the way. But then when the OP posts again in the thread I want someway of that being highlighted as the OP, maybe something like "Story Update". So users can skim through the thread of say 20 posts and quickly see the OPs contribution to the story / case study development.
