Moderators will retitle, relocate, split, lock, or assign "Workshop", "Feature" or other designations to notable threads as part of an overall effort to keep manage the educational platform and keep discussions active, centered and moving forward.
Retitling a thread is typically done to clarify the content of the thread for current and future members. Retitling increases member participation between 50% and 500%. Relocating a thread is done to consolidate similar topics in an area where they will get the most qualified responses. Splitting a thread is generally to protect a host's topic from being redirected to another topic or refocused on another member (hijacking), to highlight or draw attention to a significant member issue or topic that might otherwise be lost in the run of a thread, or to welcome a newbie. Threads are locked at 30 posts to limit the size to one that is fully readable/digestible.
We have guidelines here that explain the moderation in greater detail.
