|PUBLIC_CHANNEL||Chat channel that broadcasts to all nearby users. This channel is sometimes referred to as: open chat, local chat and public chat.|
- Messages sent on channel zero and DEBUG_CHANNEL are throttled to a rate of <200/10sec, per region, per owner/user.
- Once the rate is exceeded, all following messages on channel zero or DEBUG_CHANNEL will be dropped until the send rate is again below 200/10sec for the previous 10 sec. Dropped messages, despite being dropped still count against the limit.
- listen works, where a can only be heard by any prim in the object if and only if the root prim is capable of hearing it. can only be heard within 20 meters of the speaking prim (rather than the root). This is contrary to how the event

If you are going to sell your script widely please add it to the appropriate known chat channels list so others won't interfere with your product (do keep in mind you should build your product so that it handles interference appropriately).
From at least September 2016 (see Release Notes/Second Life Release/126.96.36.1990038), viewers have been able to chat on negative channels, although chat is limited to 254 characters. Negative channels have been popular for script communications because the standard SL client was unable to chat directly on those channels (

message on channel
-xxxx). The only way for a viewer to generate chat on negative channels prior to llTextBox was to use llDialog which was limited to 24 bytes.
