Pre Channels
A pre channel is an IRC channel in which a bot (prebot) announces new topsite warez (pre) releases in real time. Pre channels are generally provided as a convenience to members of the scene, often in conjunction with a topsite. Pre channels are typically private.

Advantages
- Members of a pre channel are notified about new warez releases as they are released. This is of particular benefit to couriers and release groups.
- Pre channels commonly announce when a release is nuked or un-nuked.
- Pre channels provide a search facility that allows users to find out if a release exists, when it was released, and if it has been nuked. This function may also be used by release groups to avoid dupes (duplicates).
- Pre channels are also used for Topsites to measure how fast they received the release, otherwise known as the pretime.
Disadvantages
- Pre channels are often supplied with events from other pre channels, so spam may spread quickly. Many prebots employ elaborate filters to ensure only valid release events are announced.
