Techopedia Explains LatecomerA groupware system requires a basic mechanism that allows latecomers to attain a system's current state via a replay describing how a current state was attained. This mechanism logs modifying events in a history list. This list is replayed to latecomers with a current activity status. If an event depends on external information, it can be difficult to replay a log correctly.

- It can potentially consume too much memory space.
- A complete replay consumes time.
